This file is part of bzip2/libbzip2, a program and library for
lossless, block-sorting data compression.
bzip2/libbzip2 version 1.0.6 of 6 September 2010
Copyright (C) 1996-2010 Julian Seward <jseward@bzip.org>
Please read the WARNING, DISCLAIMER and PATENTS sections in the
README file.
This program is released under the terms of the license contained
in the file LICENSE.
------------------------------------------------------------------
0.9.0
~~~~~
First version.
0.9.0a
~~~~~~
Removed 'ranlib' from Makefile, since most modern Unix-es
don't need it, or even know about it.
0.9.0b
~~~~~~
Fixed a problem with error reporting in bzip2.c. This does not effect
the library in any way. Problem is: versions 0.9.0 and 0.9.0a (of the
program proper) compress and decompress correctly, but give misleading
error messages (internal panics) when an I/O error occurs, instead of
reporting the problem correctly. This shouldn't give any data loss
(as far as I can see), but is confusing.
Made the inline declarations disappear for non-GCC compilers.
0.9.0c
~~~~~~
Fixed some problems in the library pertaining to some boundary cases.
This makes the library behave more correctly in those situations. The
fixes apply only to features (calls and parameters) not used by
bzip2.c, so the non-fixedness of them in previous versions has no
effect on reliability of bzip2.c.
In bzlib.c:
* made zero-length BZ_FLUSH work correctly in bzCompress().
* fixed bzWrite/bzRead to ignore zero-length requests.
* fixed bzread to correctly handle read requests after EOF.
* wrong parameter order in call to bzDecompressInit in
bzBuffToBuffDecompress. Fixed.
In compress.c:
* changed setting of nGroups in sendMTFValues() so as to
do a bit better on small files. This _does_ effect
bzip2.c.
0.9.5a
~~~~~~
Major change: add a fallback sorting algorithm (blocksort.c)
to give reasonable behaviour even for very repetitive inputs.
Nuked --repetitive-best and --repetitive-fast since they are
no longer useful.
Minor changes: mostly a whole bunch of small changes/
bugfixes in the driver (bzip2.c). Changes pertaining to the
user interface are:
allow decompression of symlink'd files to stdout
decompress/test files even without .bz2 extension
give more accurate error messages for I/O errors
when compressing/decompressing to stdout, don't catch control-C
read flags from BZIP2 and BZIP environment variables
decline to break hard links to a file unless forced with -f
allow -c flag even with no filenames
preserve file ownerships as far as possible
make -s -1 give the expected block size (100k)
add a flag -q --quiet to suppress nonessential warnings
stop decoding flags after --, so files beginning in - can be handled
resolved inconsistent naming: bzcat or bz2cat ?
bzip2 --help now returns 0
Programming-level changes are:
fixed syntax error in GET_LL4 for Borland C++ 5.02
let bzBuffToBuffDecompress return BZ_DATA_ERROR{_MAGIC}
fix overshoot of mode-string end in bzopen_or_bzdopen
wrapped bzlib.h in #ifdef __cplusplus ... extern "C" { ... }
close file handles under all error conditions
added minor mods so it compiles with DJGPP out of the box
fixed Makefile so it doesn't give problems with BSD make
fix uninitialised memory reads in dlltest.c
0.9.5b
~~~~~~
Open stdin/stdout in binary mode for DJGPP.
0.9.5c
~~~~~~
Changed BZ_N_OVERSHOOT to be ... + 2 instead of ... + 1. The + 1
version could cause the sorted order to be wrong in some extremely
obscure cases. Also changed setting of quadrant in blocksort.c.
0.9.5d
~~~~~~
The only functional change is to make bzlibVersion() in the library
return the correct string. This has no effect whatsoever on the
functioning of the bzip2 program or library. Added a couple of casts
so the library compiles without warnings at level 3 in MS Visual
Studio 6.0. Included a Y2K statement in the file Y2K_INFO. All other
changes are minor documentation changes.
1.0
~~~
Several minor bugfixes and enhancements:
* Large file support. The library uses 64-bit counters to
count the volume of data passing through it. bzip2.c
is now compiled with -D_FILE_OFFSET_BITS=64 to get large
file support from the C library. -v correctly prints out
file sizes greater than 4 gigabytes. All these changes have
been made without assuming a 64-bit platform or a C compiler
which supports 64-bit ints, so, except for the C library
aspect, they are fully portable.
* Decompression robustness. The library/program should be
robust to any corruption of compressed data, detecting and
handling _all_ corruption, instead of merely relying on
the CRCs. What this means is that the program should
never crash, given corrupted data, and the library should
always return BZ_DATA_ERROR.
* Fixed an obscure race-condition bug only ever observed on
Solaris, in which, if you were very unlucky and issued
control-C at exactly the wrong time, both input and output
files would be deleted.
* Don't run out of file handles on test/decompression when
large numbers of files have invalid magic numbers.
* Avoid library namespace pollution. Prefix all exported
symbols with BZ2_.
* Minor sorting enhancements from my DCC2000 paper.
* Advance the version number to 1.0, so as to counteract the
(false-in-this-case) impression some people have that programs
with version numbers less than 1.0 are in some way, experimental,
pre-release versions.
* Create an initial Makefile-libbz2_so to build a shared library.
Yes, I know I should really use libtool et al ...
* Make the program exit with 2 instead of 0 when decompression
fails due to a bad magic number (ie, an invalid bzip2 header).
Also exit with 1 (as the manual claims :-) whenever a diagnostic
message would have been printed AND the corresponding operation
is aborted, for example
bzip2: Output file xx already exists.
When a diagnostic message is printed but the operation is not
aborted, for example
bzip2: Can't guess original name for wurble -- using wurble.out
then the exit value 0 is returned, unless some other problem is
also detected.
I think it corresponds more closely to what the manual claims now.
1.0.1
~~~~~
* Modified dlltest.c so it uses the new BZ2_ naming scheme.
* Modified makefile-msc to fix minor build probs on Win2k.
* Updated README.COMPILATION.PROBLEMS.
There are no functionality changes or bug fixes relative to version
1.0.0. This is just a documentation update + a fix for minor Win32
build problems. For almost everyone, upgrading from 1.0.0 to 1.0.1 is
utterly pointless. Don't bother.
1.0.2
~~~~~
A bug fix release, addressing various minor issues which have appeared
in the 18 or so months since 1.0.1 was released. Most of the fixes
are to do with file-handling or documentation bugs. To the best of my
knowledge, there have been no data-loss-causing bugs reported in the
compression/decompression engine of 1.0.0 or 1.0.1.
Note that this release does not improve the rather crude build system
for Unix platforms. The general plan here is to autoconfiscate/
libtoolise 1.0.2 soon after release, and release the result as 1.1.0
or perhaps 1.2.0. That, however, is still just a plan at this point.
Here are the changes in 1.0.2. Bug-reporters and/or patch-senders in
parentheses.
* Fix an infinite segfault loop in 1.0.1 when a directory is
encountered in -f (force) mode.
(Trond Eivind Glomsrod, Nicholas Nethercote, Volker Schmidt)
* Avoid double fclose() of output file on certain I/O error paths.
(Solar Designer)
* Don't fail with internal error 1007 when fed a long stream (> 48MB)
of byte 251. Also print useful message suggesting that 1007s may be
caused by bad memory.
(noticed by Juan Pedro Vallejo, fixed by me)
* Fix uninitialised variable silly bug in demo prog dlltest.c.
(Jorj Bauer)
* Remove 512-MB limitation on recovered file size for bzip2recover
on selected platforms which support 64-bit ints. At the moment
all GCC supported platforms, and Win32.
(me, Alson van der Meulen)
* Hard-code header byte values, to give correct operation on platforms
using EBCDIC as their native character set (IBM's OS/390).
(Leland Lucius)
* Copy file access times correctly.
(Marty Leisner)
* Add distclean and check targets to Makefile.
(Michael Carmack)
* Parameterise use of ar and ranlib in Makefile. Also add $(LDFLAGS).
(Rich Ireland, Bo Thorsen)
* Pass -p (create parent dirs as needed) to mkdir during make install.
(Jeremy Fusco)
* Dereference symlinks when copying file permissions in -f mode.
(Volker Schmidt)
* Majorly simplify implementation of uInt64_qrm10.
(Bo Lindbergh)
* Check the input file still exists before deleting the output one,
when aborting in cleanUpAndFail().
(Joerg Prante, Robert Linden, Matthias Krings)
Also a bunch of patches courtesy of Philippe Troin, the Debian maintainer
of bzip2:
* Wrapper scripts (with manpages): bzdiff, bzgrep, bzmore.
* Spelling changes and minor enhancements in bzip2.1.
* Avoid race condition between creating the output file and setting its
interim permissions safely, by using fopen_output_safely().
No changes to bzip2recover since there is no issue with file
permissions there.
* do not print senseless report with -v when compressing an empty
file.
* bzcat -f works on non-bzip2 files.
* do not try to escape shell meta-characters on unix (the shell takes
care of these).
* added --fast and --best aliases for -1 -9 for gzip compatibility.
1.0.3 (15 Feb 05)
~~~~~~~~~~~~~~~~~
Fixes some minor bugs since the last version, 1.0.2.
* Further robustification against corrupted compressed data.
There are currently no known bitstreams which can cause the
decompressor to crash, loop or access memory which does not
belong to it. If you are using bzip2 or the library to
decompress bitstreams from untrusted sources, an upgrade
to 1.0.3 is recommended. This fixes CAN-2005-1260.
* The documentation has been converted to XML, from which html
and pdf can be derived.
* Various minor bugs in the documentation have been fixed.
* Fixes for various compilation warnings with newer versions of
gcc, and on 64-bit platforms.
* The BZ_NO_STDIO cpp symbol was not properly observed in 1.0.2.
This has been fixed.
1.0.4 (20 Dec 06)
~~~~~~~~~~~~~~~~~
Fixes some minor bugs since the last version, 1.0.3.
* Fix file permissions race problem (CAN-2005-0953).
* Avoid possible segfault in BZ2_bzclose. From Coverity's NetBSD
scan.
* 'const'/prototype cleanups in the C code.
* Change default install location to /usr/local, and handle multiple
'make install's without error.
* Sanitise file names more carefully in bzgrep. Fixes CAN-2005-0758
to the extent that applies to bzgrep.
* Use 'mktemp' rather than 'tempfile' in bzdiff.
* Tighten up a couple of assertions in blocksort.c following automated
analysis.
* Fix minor doc/comment bugs.
1.0.5 (10 Dec 07)
~~~~~~~~~~~~~~~~~
Security fix only. Fixes CERT-FI 20469 as it applies to bzip2.
1.0.6 (6 Sept 10)
~~~~~~~~~~~~~~~~~
* Security fix for CVE-2010-0405. This was reported by Mikolaj
Izdebski.
* Make the documentation build on Ubuntu 10.04

Workaround: avoid using pthread_exit() in C++ applications. Exit

2. Cancellation problems in optimised code
2. Cancellation problems in C++ builds
- Milan Gardian
[Note: It's not clear if this problem isn't simply due to the context
switch in pthread_cancel() which occurs unless the QueueUserAPCEx
library and driver are installed and used. Just like setjmp/longjmp,
this is probably not going to work well in C++. In any case, unless for
some very unusual reason you really must use the C++ build then please
use the C build pthreadVC2.dll or pthreadGC2.dll, i.e. for C++
applications.]
This is suspected to be a compiler bug in VC6.0, and also seen in
VC7.0 and VS .NET 2003. The GNU C++ compiler does not have a problem
with this, and it has been reported that the Intel C++ 8.1 compiler

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>

You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

------------------------------------------------------------------------------
Q 11 Why isn't pthread_t defined as a scalar (e.g. pointer or int)
like it is for other POSIX threads implementations?
----
Originally pthread_t was defined as a pointer (to the opaque pthread_t_
struct) and later it was changed to a struct containing the original
pointer plus a sequence counter. This is allowed under both the original
POSIX Threads Standard and the current Single Unix Specification.
When pthread_t is a simple pointer to a struct some very difficult to
debug problems arise from the process of freeing and later allocing
thread structs because new pthread_t handles can acquire the identity of
previously detached threads. The change to a struct was made, along with
some changes to their internal managment, in order to guarantee (for
practical applications) that the pthread_t handle will be unique over the
life of the running process.
Where application code attempts to compare one pthread_t against another
directly, a compiler error will be emitted because structs can't be
compared at that level. This should signal a potentially serious problem
in the code design, which would go undetected if pthread_t was a scalar.
The POSIX Threading API provides a function named pthread_equal() to
compare pthread_t thread handles.
Other pthreads implementations, such as Sun's, use an int as the handle
but do guarantee uniqueness within the process scope. Win32 scalar typed
thread handles also guarantee uniqueness in system scope. It wasn't clear
how well the internal management of these handles would scale as the
number of threads and the fragmentation of the sequence numbering
increased for applications where thousands or millions of threads are
created and detached over time. The current management of threads within
pthreads-win32 using structs for pthread_t, and reusing without ever
freeing them, reduces the management time overheads to a constant, which
could be important given that pthreads-win32 threads are built on top of
Win32 threads and will therefore include that management overhead on top
of their own. The cost is that the memory resources used for thread
handles will remain at the peak level until the process exits.
While it may be inconvenient for developers to be forced away from making
assumptions about the internals of pthread_t, the advantage for the
future development of pthread-win32, as well as those applications that
use it and other pthread implementations, is that the library is free to
change pthread_t internals and management as better methods arise.

# The library can be built with some alternative behaviour to
# facilitate development of applications on Win32 that will be ported

# non-compliant, but applications that make assumptions that POSIX
# does not garrantee may fail or misbehave under some settings.
#
# PTW32_THREAD_ID_REUSE_INCREMENT
# Purpose:
# POSIX says that applications should assume that thread IDs can be
# recycled. However, Solaris and some other systems use a [very large]
# sequence number as the thread ID, which provides virtual uniqueness.
# Pthreads-win32 provides pseudo-unique IDs when the default increment
# (1) is used, but pthread_t is not a scalar type like Solaris's.
#
# Usage:
# Set to any value in the range: 0 <= value <= 2^wordsize
#
# Examples:
# Set to 0 to emulate non recycle-unique behaviour like Linux or *BSD.
# Set to 1 for recycle-unique thread IDs (this is the default).
# Set to some other +ve value to emulate smaller word size types
# (i.e. will wrap sooner).

RELEASE 2.9.0
-------------
(2012-05-25)
General
-------
New bug fixes in this release since 2.8.0 have NOT been applied to the
1.x.x series.
Some changes post 2011-02-26 in CVS may not be compatible with pre
Windows 2000 systems.
Use of other than the "C" version of the library is now discouraged.
That is, the "C++" version fails some tests and does not provide any
additional functionality.
Testing and verification
------------------------
This version has been tested on SMP architecture (Intel x64 Hex Core)
by completing the included test suite, stress and bench tests.
New Features
------------
DLL properties now properly includes the target architecture, i.e.
right-click on the file pthreadVC2.dll in explorer and choose the Detail
tab will show the compiler and architecture in the description field, e.g.
"MS C x64" or "MS C x86".
- Ross Johnson
(MSC and GNU builds) The statically linked library now automatically
initialises and cleans up on program start/exit, i.e. statically linked
applications need not call the routines pthread_win32_process_attach_np()
and pthread_win32_process_detach_np() explicitly. The per-thread routine
pthread_win32_thread_detach_np() is also called at program exit to cleanup
POSIX resources acquired by the primary Windows native thread, if I (RJ)
understand the process correctly. Other Windows native threads that call
POSIX API routines may need to call the thread detach routine on thread
exit if the application depends on reclaimed POSIX resources or running
POSIX TSD (TLS) destructors.
See README.NONPORTABLE for descriptions of these routines.

Robust mutexes are implemented within the PROCESS_PRIVATE scope. NOTE that
pthread_mutex_* functions may return different error codes for robust
mutexes than they otherwise do in normal usage, e.g. pthread_mutex_unlock
is required to check ownership for all mutex types when the mutex is
robust, whereas this does not occur for the "normal" non-robust mutex type.
- Ross Johnson
pthread_getunique_np is implemented for source level compatibility
with some other implementations. This routine returns a 64 bit
sequence number that is uniquely associated with a thread. It can be
used by applications to order or hash POSIX thread handles.
- Ross Johnson
Bug fixes
---------
Many more changes for 64 bit systems.
- Kai Tietz
Various modifications and fixes to build and test for WinCE.
- Marcel Ruff, Sinan Kaya
Fix pthread_cond_destroy() - should not be a cancellation point. Other
minor build problems fixed.
- Romano Paolo Tenca
Remove potential deadlock condition from pthread_cond_destroy().
- Eric Berge
Various modifications to build and test for Win64.
- Kip Streithorst
Various fixes to the QueueUserAPCEx async cancellation helper DLL
(this is a separate download) and pthreads code cleanups.
- Sebastian Gottschalk
Removed potential NULL pointer reference.
- Robert Kindred
Removed the requirement that applications restrict the number of threads
calling pthread_barrier_wait to just the barrier count. Also reduced the
contention between barrier_wait and barrier_destroy. This change will have
slowed barriers down slightly but halves the number of semaphores consumed
per barrier to one.
- Ross Johnson
Fixed a handle leak in sched_[gs]etscheduler.
- Mark Pizzolato
Removed all of the POSIX re-entrant function compatibility macros from pthread.h.
Some were simply not semanticly correct.
- Igor Lubashev
Threads no longer attempt to pass uncaught exceptions out of thread scope (C++
and SEH builds only). Uncaught exceptions now cause the thread to exit with
the return code PTHREAD_CANCELED.
- Ross Johnson
Lots of casting fixes particularly for x64, Interlocked fixes and reworking
for x64.
- Daniel Richard G., John Kamp
Other changes
-------------
Dependence on the winsock library is now discretionary via
#define RETAIN_WSALASTERROR in config.h. It is undefined by default unless
WINCE is defined (because RJ is unsure of the dependency there).
- Ramiro Polla
Several static POSIX mutexes used for internal management were replaced by
MCS queue-based locks to reduce resource consumption, in particular use of Win32
objects.
- Ross Johnson
For security, the QuserEx.dll if used must now be installed in the Windows System
folder.
- Ross Johnson
New tests
---------
robust[1-5].c - Robust mutexes
sequence1.c - per-thread unique sequence numbers
Modified tests and benchtests
-----------------------------
All mutex*.c tests wherever appropriate have been modified to also test
robust mutexes under the same conditions.
Added robust mutex benchtests to benchtest*.c wherever appropriate.
RELEASE 2.8.0

3rdparty/pthreads4w/README.Borland vendored Normal file
View File

@ -0,0 +1,57 @@
In ptw32_InterlockedCompareExchange.c, I've added a section for
Borland's compiler; it's identical to that for the MS compiler except
that it uses /* ... */ comments instead of ; comments.
[RPJ: need to define HAVE_TASM32 in config.h to use the above.]
The other file is a makefile suitable for use with Borland's compiler
(run "make -fBmakefile" in the directory). It builds a single version
of the library, pthreadBC.dll and the corresponding pthreadBC.lib
import library, which is comparable to the pthreadVC version; I can't
personally see any demand for the versions that include structured or
C++ exception cancellation handling so I haven't attempted to build
those versions of the library. (I imagine a static version might be
of use to some, but we can't legally use that on my commercial
projects so I can't try that out, unfortunately.)
[RPJ: Added tests\Bmakefile as well.]
Borland C++ doesn't define the ENOSYS constant used by pthreads-win32;
rather than make more extensive patches to the pthreads-win32 source I
have a mostly-arbitrary constant for it in the makefile. However this
doesn't make it visible to the application using the library, so if
anyone actually wants to use this constant in their apps (why?)
someone might like to make a seperate NEED_BCC_something define to add
this stuff.
The makefile also #defines EDEADLK as EDEADLOCK, _timeb as timeb, and
_ftime as ftime, to deal with the minor differences between the two
RTLs' naming conventions, and sets the compiler flags as required to
get a normal compile of the library.
[RPJ: Moved errno values and _timeb etc to pthread.h, so apps will also
use them.]
(While I'm on the subject, the reason Borland users should recompile
the library, rather than using the impdef/implib technique suggested
previously on the mailing list, is that a) the errno constants are
different, so the results returned by the pthread_* functions can be
meaningless, and b) the errno variable/pseudo-variable itself is
different in the MS & BCC runtimes, so you can't access the
pthreadVC's errno from a Borland C++-compiled host application
correctly - I imagine there are other potential problems from the RTL
mismatch too.)
[RPJ: Make sure you use the same RTL in both dll and application builds.
The dll and tests Bmakefiles use cw32mti.lib. Having some trouble with
memory read exceptions running the test suite using BCC55.]

Will

This file documents non-portable functions and other issues.
Non-portable functions included in pthreads-win32
-------------------------------------------------
BOOL
pthread_win32_test_features_np(int mask)
This routine allows an application to check which
run-time auto-detected features are available within
the library.
The possible features are:
PTW32_SYSTEM_INTERLOCKED_COMPARE_EXCHANGE
Return TRUE if the native version of
InterlockedCompareExchange() is being used.
This feature is not meaningful in recent
library versions as MSVC builds only support
system implemented ICE. Note that all Mingw
builds use inlined asm versions of all the
Interlocked routines.
PTW32_ALERTABLE_ASYNC_CANCEL
Return TRUE is the QueueUserAPCEx package
QUSEREX.DLL is available and the AlertDrv.sys
driver is loaded into Windows, providing
alertable (pre-emptive) asyncronous threads
cancelation. If this feature returns FALSE
then the default async cancel scheme is in
use, which cannot cancel blocked threads.
Features may be Or'ed into the mask parameter, in which case
the routine returns TRUE if any of the Or'ed features would
return TRUE. At this stage it doesn't make sense to Or features
but it may some day.
void *
pthread_timechange_handler_np(void *)
To improve tolerance against operator or time service
initiated system clock changes.
This routine can be called by an application when it
receives a WM_TIMECHANGE message from the system. At
present it broadcasts all condition variables so that
waiting threads can wake up and re-evaluate their
conditions and restart their timed waits if required.
It has the same return type and argument type as a
thread routine so that it may be called directly
through pthread_create(), i.e. as a separate thread.
Parameters
Although a parameter must be supplied, it is ignored.
The value NULL can be used.
Return values
It can return an error EAGAIN to indicate that not
all condition variables were broadcast for some reason.
Otherwise, 0 is returned.
If run as a thread, the return value is returned
through pthread_join().
The return value should be cast to an integer.
HANDLE
pthread_getw32threadhandle_np(pthread_t thread);
Returns the win32 thread handle that the POSIX
thread "thread" is running as.
Applications can use the win32 handle to set
win32 specific attributes of the thread.
DWORD
pthread_getw32threadid_np (pthread_t thread)
Returns the Windows native thread ID that the POSIX
thread "thread" is running as.
Only valid when the library is built where
! (defined(__MINGW64__) || defined(__MINGW32__)) || defined (__MSVCRT__) || defined (__DMC__)
and otherwise returns 0.
int
pthread_mutexattr_setkind_np(pthread_mutexattr_t * attr, int kind)
int
pthread_mutexattr_getkind_np(pthread_mutexattr_t * attr, int *kind)
These two routines are included for Linux compatibility
and are direct equivalents to the standard routines
pthread_mutexattr_settype
pthread_mutexattr_gettype
pthread_mutexattr_setkind_np accepts the following
mutex kinds:
PTHREAD_MUTEX_FAST_NP
PTHREAD_MUTEX_ERRORCHECK_NP
PTHREAD_MUTEX_RECURSIVE_NP
These are really just equivalent to (respectively):
PTHREAD_MUTEX_NORMAL
PTHREAD_MUTEX_ERRORCHECK
PTHREAD_MUTEX_RECURSIVE
int
pthread_delay_np (const struct timespec *interval);
This routine causes a thread to delay execution for a specific period of time.
This period ends at the current time plus the specified interval. The routine
will not return before the end of the period is reached, but may return an
arbitrary amount of time after the period has gone by. This can be due to
system load, thread priorities, and system timer granularity.
Specifying an interval of zero (0) seconds and zero (0) nanoseconds is
allowed and can be used to force the thread to give up the processor or to
deliver a pending cancelation request.
This routine is a cancelation point.
The timespec structure contains the following two fields:
tv_sec is an integer number of seconds.
tv_nsec is an integer number of nanoseconds.
Return Values
If an error condition occurs, this routine returns an integer value
indicating the type of error. Possible return values are as follows:
0 Successful completion.
[EINVAL] The value specified by interval is invalid.
int
pthread_num_processors_np (void)
This routine (found on HPUX systems) returns the number of processors
in the system. This implementation actually returns the number of
processors available to the process, which can be a lower number
than the system's number, depending on the process's affinity mask.
BOOL
pthread_win32_process_attach_np (void);
BOOL
pthread_win32_process_detach_np (void);
BOOL
pthread_win32_thread_attach_np (void);
BOOL
pthread_win32_thread_detach_np (void);
These functions contain the code normally run via dllMain
when the library is used as a dll but which need to be
called explicitly by an application when the library
is statically linked. As of version 2.9.0 of the library, static
builds using either MSC or GCC will call pthread_win32_process_*
automatically at application startup and exit respectively.
Otherwise, you will need to call pthread_win32_process_attach_np()
before you can call any pthread routines when statically linking.
You should call pthread_win32_process_detach_np() before
exiting your application to clean up.
pthread_win32_thread_attach_np() is currently a no-op, but
pthread_win32_thread_detach_np() is needed to clean up
the implicit pthread handle that is allocated to a Win32 thread if
it calls any pthreads routines. Call this routine when the
Win32 thread exits.
Threads created through pthread_create() do not need to call
pthread_win32_thread_detach_np().
These functions invariably return TRUE except for
pthread_win32_process_attach_np() which will return FALSE
if pthreads-win32 initialisation fails.
int
pthreadCancelableWait (HANDLE waitHandle);
int
pthreadCancelableTimedWait (HANDLE waitHandle, DWORD timeout);
These two functions provide hooks into the pthread_cancel
mechanism that will allow you to wait on a Windows handle
and make it a cancellation point. Both functions block
until either the given w32 handle is signaled, or
pthread_cancel has been called. It is implemented using
WaitForMultipleObjects on 'waitHandle' and a manually
reset w32 event used to implement pthread_cancel.
Non-portable issues
-------------------
Thread priority
POSIX defines a single contiguous range of numbers that determine a
thread's priority. Win32 defines priority classes and priority
levels relative to these classes. Classes are simply priority base
levels that the defined priority levels are relative to such that,
changing a process's priority class will change the priority of all
of it's threads, while the threads retain the same relativity to each
other.
A Win32 system defines a single contiguous monotonic range of values
that define system priority levels, just like POSIX. However, Win32
restricts individual threads to a subset of this range on a
per-process basis.
The following table shows the base priority levels for combinations
of priority class and priority value in Win32.

30 REALTIME_PRIORITY_CLASS 6
31 REALTIME_PRIORITY_CLASS THREAD_PRIORITY_TIME_CRITICAL
Windows NT: Values -7, -6, -5, -4, -3, 3, 4, 5, and 6 are not supported.
As you can see, the real priority levels available to any individual
Win32 thread are non-contiguous.
An application using pthreads-win32 should not make assumptions about
the numbers used to represent thread priority levels, except that they
are monotonic between the values returned by sched_get_priority_min()
and sched_get_priority_max(). E.g. Windows 95, 98, NT, 2000, XP make
available a non-contiguous range of numbers between -15 and 15, while
at least one version of WinCE (3.0) defines the minimum priority
(THREAD_PRIORITY_LOWEST) as 5, and the maximum priority
(THREAD_PRIORITY_HIGHEST) as 1.
Internally, pthreads-win32 maps any priority levels between
THREAD_PRIORITY_IDLE and THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST,
or between THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
THREAD_PRIORITY_HIGHEST. Currently, this also applies to
REALTIME_PRIORITY_CLASSi even if levels -7, -6, -5, -4, -3, 3, 4, 5, and 6
are supported.
If it wishes, a Win32 application using pthreads-win32 can use the Win32
defined priority macros THREAD_PRIORITY_IDLE through
THREAD_PRIORITY_TIME_CRITICAL.
The opacity of the pthread_t datatype
-------------------------------------
and possible solutions for portable null/compare/hash, etc
----------------------------------------------------------
Because pthread_t is an opague datatype an implementation is permitted to define
pthread_t in any way it wishes. That includes defining some bits, if it is
scalar, or members, if it is an aggregate, to store information that may be
extra to the unique identifying value of the ID. As a result, pthread_t values
may not be directly comparable.
If you want your code to be portable you must adhere to the following contraints:
1) Don't assume it is a scalar data type, e.g. an integer or pointer value. There
are several other implementations where pthread_t is also a struct. See our FAQ
Question 11 for our reasons for defining pthread_t as a struct.
2) You must not compare them using relational or equality operators. You must use
the API function pthread_equal() to test for equality.
3) Never attempt to reference individual members.
The problem
Certain applications would like to be able to access only the 'pure' pthread_t
id values, primarily to use as keys into data structures to manage threads or
thread-related data, but this is not possible in a maximally portable and
standards compliant way for current POSIX threads implementations.
For implementations that define pthread_t as a scalar, programmers often employ
direct relational and equality operators on pthread_t. This code will break when
ported to an implementation that defines pthread_t as an aggregate type.
For implementations that define pthread_t as an aggregate, e.g. a struct,
programmers can use memcmp etc., but then face the prospect that the struct may
include alignment padding bytes or bits as well as extra implementation-specific
members that are not part of the unique identifying value.
[While this is not currently the case for pthreads-win32, opacity also
means that an implementation is free to change the definition, which should
generally only require that applications be recompiled and relinked, not
rewritten.]
Doesn't the compiler take care of padding?
The C89 and later standards only effectively guarrantee element-by-element
equivalence following an assignment or pass by value of a struct or union,
therefore undefined areas of any two otherwise equivalent pthread_t instances
can still compare differently, e.g. attempting to compare two such pthread_t
variables byte-by-byte, e.g. memcmp(&t1, &t2, sizeof(pthread_t) may give an
incorrect result. In practice I'm reasonably confident that compilers routinely
also copy the padding bytes, mainly because assignment of unions would be far
too complicated otherwise. But it just isn't guarranteed by the standard.
Illustration:
We have two thread IDs t1 and t2
pthread_t t1, t2;
In an application we create the threads and intend to store the thread IDs in an
ordered data structure (linked list, tree, etc) so we need to be able to compare
them in order to insert them initially and also to traverse.
Suppose pthread_t contains undefined padding bits and our compiler copies our
pthread_t [struct] element-by-element, then for the assignment:
pthread_t temp = t1;
temp and t1 will be equivalent and correct but a byte-for-byte comparison such as
memcmp(&temp, &t1, sizeof(pthread_t)) == 0 may not return true as we expect because
the undefined bits may not have the same values in the two variable instances.
Similarly if passing by value under the same conditions.
If, on the other hand, the undefined bits are at least constant through every
assignment and pass-by-value then the byte-for-byte comparison
memcmp(&temp, &t1, sizeof(pthread_t)) == 0 will always return the expected result.
How can we force the behaviour we need?
Solutions
Adding new functions to the standard API or as non-portable extentions is
the only reliable and portable way to provide the necessary operations.
Remember also that POSIX is not tied to the C language. The most common
functions that have been suggested are:
pthread_null()
pthread_compare()
pthread_hash()
A single more general purpose function could also be defined as a
basis for at least the last two of the above functions.
First we need to list the freedoms and constraints with restpect
to pthread_t so that we can be sure our solution is compatible with the
standard.
What is known or may be deduced from the standard:
1) pthread_t must be able to be passed by value, so it must be a single object.
2) from (1) it must be copyable so cannot embed thread-state information, locks
or other volatile objects required to manage the thread it associates with.
3) pthread_t may carry additional information, e.g. for debugging or to manage
itself.
4) there is an implicit requirement that the size of pthread_t is determinable
at compile-time and size-invariant, because it must be able to copy the object
(i.e. through assignment and pass-by-value). Such copies must be genuine
duplicates, not merely a copy of a pointer to a common instance such as
would be the case if pthread_t were defined as an array.
Suppose we define the following function:
/* This function shall return it's argument */
pthread_t* pthread_normalize(pthread_t* thread);
For scalar or aggregate pthread_t types this function would simply zero any bits
within the pthread_t that don't uniquely identify the thread, including padding,
such that client code can return consistent results from operations done on the
result. If the additional bits are a pointer to an associate structure then
this function would ensure that the memory used to store that associate
structure does not leak. After normalization the following compare would be
valid and repeatable:
memcmp(pthread_normalize(&t1),pthread_normalize(&t2),sizeof(pthread_t))
Note 1: such comparisons are intended merely to order and sort pthread_t values
and allow them to index various data structures. They are not intended to reveal
anything about the relationships between threads, like startup order.
Note 2: the normalized pthread_t is also a valid pthread_t that uniquely
identifies the same thread.
Advantages:
1) In most existing implementations this function would reduce to a no-op that
emits no additional instructions, i.e after in-lining or optimisation, or if
defined as a macro:
#define pthread_normalise(tptr) (tptr)
2) This single function allows an application to portably derive
application-level versions of any of the other required functions.
3) It is a generic function that could enable unanticipated uses.
Disadvantages:
1) Less efficient than dedicated compare or hash functions for implementations
that include significant extra non-id elements in pthread_t.
2) Still need to be concerned about padding if copying normalized pthread_t.
See the later section on defining pthread_t to neutralise padding issues.
Generally a pthread_t may need to be normalized every time it is used,
which could have a significant impact. However, this is a design decision
for the implementor in a competitive environment. An implementation is free
to define a pthread_t in a way that minimises or eliminates padding or
renders this function a no-op.
Hazards:
1) Pass-by-reference directly modifies 'thread' so the application must
synchronise access or ensure that the pointer refers to a copy. The alternative
of pass-by-value/return-by-value was considered but then this requires two copy
operations, disadvantaging implementations where this function is not a no-op
in terms of speed of execution. This function is intended to be used in high
frequency situations and needs to be efficient, or at least not unnecessarily
inefficient. The alternative also sits awkwardly with functions like memcmp.
2) [Non-compliant] code that uses relational and equality operators on
arithmetic or pointer style pthread_t types would need to be rewritten, but it
should be rewritten anyway.

pthread_t id = thread, non-id = thread;
bitclear((void*) &non-id, (void*) pthread_normalize(&id), sizeof(pthread_t));
A pthread_t type change proposal to neutralise the effects of padding
Even if pthread_nornalize() is available, padding is still a problem because
the standard only garrantees element-by-element equivalence through
copy operations (assignment and pass-by-value). So padding bit values can
still change randomly after calls to pthread_normalize().
[I suspect that most compilers take the easy path and always byte-copy anyway,
partly because it becomes too complex to do (e.g. unions that contain sub-aggregates)
but also because programmers can easily design their aggregates to minimise and
often eliminate padding].
How can we eliminate the problem of padding bytes in structs? Could
defining pthread_t as a union rather than a struct provide a solution?
In fact, the Linux pthread.h defines most of it's pthread_*_t objects (but not
pthread_t itself) as unions, possibly for this and/or other reasons. We'll
borrow some element naming from there but the ideas themselves are well known
- the __align element used to force alignment of the union comes from K&R's
storage allocator example.
/* Essentially our current pthread_t renamed */
typedef struct {
struct thread_state_t * __p;
long __x; /* sequence counter */
} thread_id_t;
Ensuring that the last element in the above struct is a long ensures that the
overall struct size is a multiple of sizeof(long), so there should be no trailing
padding in this struct or the union we define below.
(Later we'll see that we can handle internal but not trailing padding.)
/* New pthread_t */
typedef union {
char __size[sizeof(thread_id_t)]; /* array as the first element */
thread_id_t __tid;
long __align; /* Ensure that the union starts on long boundary */
} pthread_t;
This guarrantees that, during an assignment or pass-by-value, the compiler copies
every byte in our thread_id_t because the compiler guarrantees that the __size
array, which we have ensured is the equal-largest element in the union, retains
equivalence.
This means that pthread_t values stored, assigned and passed by value will at least
carry the value of any undefined padding bytes along and therefore ensure that
those values remain consistent. Our comparisons will return consistent results and
our hashes of [zero initialised] pthread_t values will also return consistent
results.
We have also removed the need for a pthread_null() function; we can initialise
at declaration time or easily create our own const pthread_t to use in assignments
later:
const pthread_t null_tid = {0}; /* braces are required */
pthread_t t;
...
t = null_tid;
Note that we don't have to explicitly make use of the __size array at all. It's
there just to force the compiler behaviour we want.
Partial solutions without a pthread_normalize function
An application-level pthread_null and pthread_compare proposal
(and pthread_hash proposal by extention)
In order to deal with the problem of scalar/aggregate pthread_t type disparity in
portable code I suggest using an old-fashioned union, e.g.:
Contraints:
- there is no padding, or padding values are preserved through assignment and
pass-by-value (see above);
- there are no extra non-id values in the pthread_t.
Example 1: A null initialiser for pthread_t variables...
typedef union {
unsigned char b[sizeof(pthread_t)];
pthread_t t;
} init_t;
const init_t initial = {0};
pthread_t tid = initial.t; /* init tid to all zeroes */
Example 2: A comparison function for pthread_t values
typedef union {
unsigned char b[sizeof(pthread_t)];
pthread_t t;
} pthcmp_t;
int pthcmp(pthread_t left, pthread_t right)
{
/*
* Compare two pthread handles in a way that imposes a repeatable but arbitrary
* ordering on them.
* I.e. given the same set of pthread_t handles the ordering should be the same
* each time but the order has no particular meaning other than that. E.g.
* the ordering does not imply the thread start sequence, or any other
* relationship between threads.
*
* Return values are:
* 1 : left is greater than right
* 0 : left is equal to right
* -1 : left is less than right
*/
int i;
pthcmp_t L, R;
L.t = left;
R.t = right;
for (i = 0; i < sizeof(pthread_t); i++)
{
if (L.b[i] > R.b[i])
return 1;
else if (L.b[i] < R.b[i])
return -1;
}
return 0;
}
It has been pointed out that the C99 standard allows for the possibility that
integer types also may include padding bits, which could invalidate the above
method. This addition to C99 was specifically included after it was pointed
out that there was one, presumably not particularly well known, architecture
that included a padding bit in it's 32 bit integer type. See section 6.2.6.2
of both the standard and the rationale, specifically the paragraph starting at
line 16 on page 43 of the rationale.
An aside
Certain compilers, e.g. gcc and one of the IBM compilers, include a feature
extention: provided the union contains a member of the same type as the
object then the object may be cast to the union itself.
We could use this feature to speed up the pthrcmp() function from example 2
above by casting rather than assigning the pthread_t arguments to the union, e.g.:
int pthcmp(pthread_t left, pthread_t right)
{
/*
* Compare two pthread handles in a way that imposes a repeatable but arbitrary
* ordering on them.
* I.e. given the same set of pthread_t handles the ordering should be the same
* each time but the order has no particular meaning other than that. E.g.
* the ordering does not imply the thread start sequence, or any other
* relationship between threads.
*
* Return values are:
* 1 : left is greater than right
* 0 : left is equal to right
* -1 : left is less than right
*/
int i;
for (i = 0; i < sizeof(pthread_t); i++)
{
if (((pthcmp_t)left).b[i] > ((pthcmp_t)right).b[i])
return 1;
else if (((pthcmp_t)left).b[i] < ((pthcmp_t)right).b[i])
return -1;
}
return 0;
}
Result thus far
We can't remove undefined bits if they are there in pthread_t already, but we have
attempted to render them inert for comparison and hashing functions by making them
consistent through assignment, copy and pass-by-value.
Note: Hashing pthread_t values requires that all pthread_t variables be initialised
to the same value (usually all zeros) before being assigned a proper thread ID, i.e.
to ensure that any padding bits are zero, or at least the same value for all
pthread_t. Since all pthread_t values are generated by the library in the first
instance this need not be an application-level operation.
Conclusion
I've attempted to resolve the multiple issues of type opacity and the possible
presence of undefined bits and bytes in pthread_t values, which prevent
applications from comparing or hashing pthread handles.
Two complimentary partial solutions have been proposed, one an application-level
scheme to handle both scalar and aggregate pthread_t types equally, plus a
definition of pthread_t itself that neutralises padding bits and bytes by
coercing semantics out of the compiler to eliminate variations in the values of
padding bits.
I have not provided any solution to the problem of handling extra values embedded
in pthread_t, e.g. debugging or trap information that an implementation is entitled
to include. Therefore none of this replaces the portability and flexibility of API
functions but what functions are needed? The threads standard is unlikely to
include that can be implemented by a combination of existing features and more
generic functions (several references in the threads rationale suggest this.
Therefore I propose that the following function could replace the several functions
that have been suggested in conversations:
pthread_t * pthread_normalize(pthread_t * handle);
For most existing pthreads implementations this function, or macro, would reduce to
a no-op with zero call overhead.

Watcom compiler notes
=====================
Status
------
Not yet usable. Although the library builds under Watcom it
substantially fails the test suite.
There is a working Wmakefile for wmake for the library build.
invoke as any of:
wmake -f Wmakefile clean WC
wmake -f Wmakefile clean WC-inlined
wmake -f Wmakefile clean WCE
wmake -f Wmakefile clean WCE-inlined
These build pthreadWC.dll and pthreadWCE.dll.
There is a working Wmakefile for wmake for the test suite.

wmake -f Wmakefile clean WCE
wmake -f Wmakefile clean WC-bench
wmake -f Wmakefile clean WCX-bench
wmake -f Wmakefile clean WCE-bench
Current known problems
----------------------
Library build:
The Watcom compiler uses a different default call convention to MS C or GNU C and so
applications are not compatible with pthreadVC.dll etc using pre 2003-10-14 versions
of pthread.h, sched.h, or semaphore.h. The cdecl attribute can be used on exposed
function prototypes to force compatibility with MS C built DLLs.
However, there appear to be other incompatibilities. Errno.h, for example, defines
different values for the standard C and POSIX errors to those defined by the MS C
errno.h. It may be that references to Watcom's threads compatible 'errno' do set
and return translated numbers consistently, but I have not verified this.
Watcom defines errno as a dereferenced pointer returned by the function
_get_errno_ptr(). This is similar to both the MS and GNU C environments for
multithreaded use. However, the Watcom version appears to have a number of problems:
- different threads return the same pointer value. Compare with the MS and GNU C
versions which correctly return different values (since each thread must maintain
a thread specific errno value).
- an errno value set within the DLL appears as zero in the application even though
both share the same thread.
Therefore applications built using the Watcom compiler may need to use
a Watcom built version of the library (pthreadWC.dll). If this is the case, then
the cdecl function attribute should not be required.
Application builds:
The test suite fails with the Watcom compiler.
Test semaphore1.c fails for pthreadWC.dll because errno returns 0 instead of EAGAIN.

NOTE: The comments in this file relate to the original WinCE port
done by Tristan Savatier. The semaphore routines have been
completely rewritten since (2005-04-25), having been progressively
broken more and more by changes to the library. All of the semaphore
routines implemented for W9x/WNT/2000 and up should now also work for
WinCE. Also, pthread_mutex_timedlock should now work.
Additional WinCE updates have been applied since this as well. Check the

[RPJ]
----
Some interesting news:
I have been able to port pthread-win32 to Windows-CE,
which uses a subset of the WIN32 API.
Since we intend to keep using pthread-win32 for our
Commercial WinCE developments, I would be very interested
if WinCE support could be added to the main source tree
of pthread-win32. Also, I would like to be credited
for this port :-)
Now, here is the story...
The port was performed and tested on a Casio "Cassiopeia"
PalmSize PC, which runs a MIP processor. The OS in the
Casio is WinCE version 2.11, but I used VC++ 6.0 with
the WinCE SDK for version 2.01.
I used pthread-win32 to port a heavily multithreaded
commercial application (real-time MPEG video player)
from Linux to WinCE. I consider the changes that
I have done to be quite well tested.
Overall the modifications that we had to do are minor.
The WinCE port were based on pthread-win32-snap-1999-05-30,
but I am certain that they can be integrated very easiely
to more recent versions of the source.
I have attached the modified source code:
pthread-win32-snap-1999-05-30-WinCE.
All the changes do not affect the code compiled on non-WinCE
environment, provided that the macros used for WinCE compilation
are not used, of course!
Overall description of the WinCE port:
-------------------------------------
Most of the changes had to be made in areas where
pthread-win32 was relying on some standard-C librairies
(e.g. _ftime, calloc, errno), which are not available
on WinCE. We have changed the code to use native Win32
API instead (or in some cases we made wrappers).
The Win32 Semaphores are not available,
so we had to re-implement Semaphores using mutexes
and events.
Limitations / known problems of the WinCE port:
----------------------------------------------
Not all the semaphore routines have been ported
(semaphores are defined by Posix but are not part
pf pthread). I have just done enough to make
pthread routines (that rely internally on semaphores)
work, like signal conditions.
I noticed that the Win32 threads work slightly
differently on WinCE. This may have some impact
on some tricky parts of pthread-win32, but I have
not really investigated. For example, on WinCE,
the process is killed if the main thread falls off
the bottom (or calls pthread_exit), regardless
of the existence of any other detached thread.
Microsoft manual indicates that this behavior is
deffirent from that of Windows Threads for other
Win32 platforms.
Detailed descriptions of the changes and rationals:
------------------------------------
- use a new macro NEED_ERRNO.
If defined, the code in errno.c that defines a reentrant errno
is compiled, regardless of _MT and _REENTRANT.
Rational: On WinCE, there is no support for <stdio.h>, <errno.h> or
any other standard C library, i.e. even if _MT or _REENTRANT
is defined, errno is not provided by any library. NEED_ERRNO
must be set to compile for WinCE.
------------------------------------
- In implement.h, change #include <semaphore.h> to #include "semaphore.h".
Rational: semaphore.h is provided in pthread-win32 and should not
be searched in the systems standard include. would not compile.
This change does not seem to create problems on "classic" win32
(e.g. win95).
------------------------------------
- use a new macro NEED_CALLOC.
If defined, some code in misc.c will provide a replacement
for calloc, which is not available on Win32.
------------------------------------
- use a new macro NEED_CREATETHREAD.
If defined, implement.h defines the macro _beginthreadex
and _endthreadex.
Rational: On WinCE, the wrappers _beginthreadex and _endthreadex
do not exist. The native Win32 routines must be used.
------------------------------------
- in misc.c:
#ifdef NEED_DUPLICATEHANDLE
/* DuplicateHandle does not exist on WinCE */
self->threadH = GetCurrentThread();
#else
if( !DuplicateHandle(
GetCurrentProcess(),
GetCurrentThread(),
GetCurrentProcess(),
&self->threadH,
0,
FALSE,
DUPLICATE_SAME_ACCESS ) )
{
free( self );
return (NULL);
}
#endif
Rational: On WinCE, DuplicateHandle does not exist. I could not understand
why DuplicateHandle must be used. It seems to me that getting the current
thread handle with GetCurrentThread() is sufficient, and it seems to work
perfectly fine, so maybe DuplicateHandle was just plain useless to begin with ?
------------------------------------
- In private.c, added some code at the beginning of ptw32_processInitialize
to detect the case of multiple calls to ptw32_processInitialize.
Rational: In order to debug pthread-win32, it is easier to compile
it as a regular library (it is not possible to debug DLL's on winCE).
In that case, the application must call ptw32_rocessInitialize()
explicitely, to initialize pthread-win32. It is safer in this circumstance
to handle the case where ptw32_processInitialize() is called on
an already initialized library:
int
ptw32_processInitialize (void)
{
if (ptw32_processInitialized) {
/*
* ignore if already initialized. this is useful for
* programs that uses a non-dll pthread
* library. such programs must call ptw32_processInitialize() explicitely,
* since this initialization routine is automatically called only when
* the dll is loaded.
*/
return TRUE;
}
ptw32_processInitialized = TRUE;
[...]
}
------------------------------------
- in private.c, if macro NEED_FTIME is defined, add routines to
convert timespec_to_filetime and filetime_to_timespec, and modified
code that was using _ftime() to use Win32 API instead.
Rational: _ftime is not available on WinCE. It is necessary to use
the native Win32 time API instead.
Note: the routine timespec_to_filetime is provided as a convenience and a mean
to test that filetime_to_timespec works, but it is not used by the library.
------------------------------------
- in semaphore.c, if macro NEED_SEM is defined, add code for the routines
_increase_semaphore and _decrease_semaphore, and modify significantly
the implementation of the semaphores so that it does not use CreateSemaphore.
Rational: CreateSemaphore is not available on WinCE. I had to re-implement
semaphores using mutexes and Events.
Note: Only the semaphore routines that are used by pthread are implemented
(i.e. signal conditions rely on a subset of the semaphores routines, and
this subset works). Some other semaphore routines (e.g. sem_trywait) are
not yet supported on my WinCE port (and since I don't need them, I am not
planning to do anything about them).
------------------------------------
- in tsd.c, changed the code that defines TLS_OUT_OF_INDEXES
/* TLS_OUT_OF_INDEXES not defined on WinCE */
#ifndef TLS_OUT_OF_INDEXES
#define TLS_OUT_OF_INDEXES 0xffffffff
#endif
Rational: TLS_OUT_OF_INDEXES is not defined in any standard include file
on WinCE.
------------------------------------
- added file need_errno.h
Rational: On WinCE, there is no errno.h file. need_errno.h is just a
copy of windows version of errno.h, with minor modifications due to the fact
that some of the error codes are defined by the WinCE socket library.
In pthread.h, if NEED_ERRNO is defined, the file need_errno.h is
included (instead of <errno.h>).

/*
* Purpose:
* This structure creates an association between a thread and a key.
* It is used to implement the implicit invocation of a user defined
* destroy routine for thread specific data registered by a user upon
* exiting a thread.
*
* Graphically, the arrangement is as follows, where:
*
* K - Key with destructor
* (head of chain is key->threads)
* T - Thread that has called pthread_setspecific(Kn)
* (head of chain is thread->keys)
* A - Association. Each association is a node at the
* intersection of two doubly-linked lists.
*
* T1 T2 T3
* | | |
* | | |
* K1 -----+-----A-----A----->
* | | |
* | | |
* K2 -----A-----A-----+----->
* | | |
* | | |
* K3 -----A-----+-----A----->
* | | |
* | | |
* V V V
*
* Access to the association is guarded by two locks: the key's
* general lock (guarding the row) and the thread's general
* lock (guarding the column). This avoids the need for a
* dedicated lock for each association, which not only consumes
* more handles but requires that the lock resources persist
* until both the key is deleted and the thread has called the
* destructor. The two-lock arrangement allows those resources
* to be freed as soon as either thread or key is concluded.
*
* To avoid deadlock, whenever both locks are required both the
* key and thread locks are acquired consistently in the order
* "key lock then thread lock". An exception to this exists
* when a thread calls the destructors, however, this is done
* carefully (but inelegantly) to avoid deadlock.
*
* An association is created when a thread first calls
* pthread_setspecific() on a key that has a specified
* destructor.
*
* An association is destroyed either immediately after the
* thread calls the key destructor function on thread exit, or
* when the key is deleted.
*
* Attributes:
* thread
* reference to the thread that owns the
* association. This is actually the pointer to the
* thread struct itself. Since the association is
* destroyed before the thread exits, this can never
* point to a different logical thread to the one that
* created the assoc, i.e. after thread struct reuse.
*
* key
* reference to the key that owns the association.
*
* nextKey
* The pthread_t->keys attribute is the head of a
* chain of associations that runs through the nextKey
* link. This chain provides the 1 to many relationship
* between a pthread_t and all pthread_key_t on which
* it called pthread_setspecific.
*
* prevKey
* Similarly.
*
* nextThread
* The pthread_key_t->threads attribute is the head of
* a chain of associations that runs through the
* nextThreads link. This chain provides the 1 to many
* relationship between a pthread_key_t and all the
* PThreads that have called pthread_setspecific for
* this pthread_key_t.
*
* prevThread
* Similarly.
*
* Notes:
* 1) As soon as either the key or the thread is no longer
* referencing the association, it can be destroyed. The
* association will be removed from both chains.
*
* 2) Under WIN32, an association is only created by
* pthread_setspecific if the user provided a
* destroyRoutine when they created the key.

<H3>Thread priority</H3>
<P STYLE="margin-left: 2cm">POSIX defines a single contiguous range
of numbers that determine a thread's priority. Win32 defines priority
classes - and priority levels relative to these classes. Classes are
simply priority base levels that the defined priority levels are
relative to such that, changing a process's priority class will
change the priority of all of it's threads, while the threads retain
the same relativity to each other.</P>
<P STYLE="margin-left: 2cm">A Win32 system defines a single
contiguous monotonic range of values that define system priority
levels, just like POSIX. However, Win32 restricts individual threads
to a subset of this range on a per-process basis.</P>
<P STYLE="margin-left: 2cm">The following table shows the base
priority levels for combinations of priority class and priority value
in Win32.</P>

<P STYLE="margin-left: 2cm">Windows NT: Values -7, -6, -5, -4, -3, 3,
4, 5, and 6 are not supported.</P>
<P STYLE="margin-left: 2cm">As you can see, the real priority levels
available to any individual Win32 thread are non-contiguous.</P>
<P STYLE="margin-left: 2cm">An application using Pthreads-w32 should
not make assumptions about the numbers used to represent thread
priority levels, except that they are monotonic between the values
returned by sched_get_priority_min() and sched_get_priority_max().
E.g. Windows 95, 98, NT, 2000, XP make available a non-contiguous
range of numbers between -15 and 15, while at least one version of
WinCE (3.0) defines the minimum priority (THREAD_PRIORITY_LOWEST) as
5, and the maximum priority (THREAD_PRIORITY_HIGHEST) as 1.</P>
<P STYLE="margin-left: 2cm">Internally, pthreads-win32 maps any
priority levels between THREAD_PRIORITY_IDLE and
THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST, or between
THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
THREAD_PRIORITY_HIGHEST. Currently, this also applies to
REALTIME_PRIORITY_CLASS even if levels -7, -6, -5, -4, -3, 3, 4, 5,
and 6 are supported.</P>
<P STYLE="margin-left: 2cm">If it wishes, a Win32 application using
pthreads-w32 can use the Win32 defined priority macros
THREAD_PRIORITY_IDLE through THREAD_PRIORITY_TIME_CRITICAL.</P>

<P>These two functions provide hooks into the <A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>()
mechanism that will allow you to wait on a Windows handle and make it
a cancellation point. Both functions block until either the given
Win32 <B>HANDLE</B> is signalled, or <A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>()
has been called. They are implemented using <B>WaitForMultipleObjects</B>
on <I>waitHandle</I> and the manually reset Win32 event handle that
is the target of <A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>().
These routines may be called from Win32 native threads but
<A HREF="pthread_cancel.html"><B>pthread_cancel</B></A>() will
require that thread's POSIX thread ID that the thread must retrieve
using <A HREF="pthread_self.html"><B>pthread_self</B></A>().</P>
<P><B>pthreadCancelableTimedWait</B> is the timed version that will
return with the code <B>ETIMEDOUT</B> if the interval <I>timeout</I>

<H2><A HREF="#toc2" NAME="sect2">Description</A></H2>
<P>Setting attributes for threads is achieved by filling a thread
attribute object <I>attr</I> of type <B>pthread_attr_t</B>, then
passing it as second argument to <A HREF="pthread_create.html"><B>pthread_create</B>(3)</A>
. Passing <B>NULL</B> is equivalent to passing a thread attribute
object with all attributes set to their default values.
</P>
<P><B>pthread_attr_init</B> initializes the thread attribute object
<I>attr</I> and fills it with default values for the attributes. (The
default values are listed below for each attribute.)
</P>
<P>Each attribute <I>attrname</I> (see below for a list of all
attributes) can be individually set using the function
<B>pthread_attr_set</B><I>attrname</I> and retrieved using the
function <B>pthread_attr_get</B><I>attrname.</I>
</P>
<P><B>pthread_attr_destroy</B> destroys a thread attribute object,
which must not then be reused until it is reinitialized.
</P>
<P>Attribute objects are consulted only when creating a new thread.
The same attribute object can be used for creating several threads.
Modifying an attribute object after a call to <B>pthread_create</B>
does not change the attributes of the thread previously created.
</P>
<P>The following thread attributes are supported:
</P>
<H3><A HREF="#toc3" NAME="sect3">detachstate</A></H3>
<P>Control whether the thread is created in the joinable state (value
<B>PTHREAD_CREATE_JOINABLE</B>) or in the detached state (
<B>PTHREAD_CREATE_DETACHED</B>).
</P>
<P>Default value: <B>PTHREAD_CREATE_JOINABLE</B>.
</P>
<P>In the joinable state, another thread can synchronize on the
thread termination and recover its termination code using
<A HREF="pthread_join.html"><B>pthread_join</B>(3)</A> . When a
joinable thread terminates, some of the thread resources are kept
allocated, and released only when another thread performs
<A HREF="pthread_join.html"><B>pthread_join</B>(3)</A> on that
thread.
</P>
<P>In the detached state, the thread's resources are released
immediately when it terminates. <A HREF="pthread_join.html"><B>pthread_join</B>(3)</A>
cannot be used to synchronize on the thread termination.
</P>
<P>A thread created in the joinable state can later be put in the
detached thread using <A HREF="pthread_detach.html"><B>pthread_detach</B>(3)</A>
.
</P>
<H3><A HREF="#toc4" NAME="sect4">schedpolicy</A></H3>
<P>Select the scheduling policy for the thread: one of <B>SCHED_OTHER</B>
(regular, non-real-time scheduling), <B>SCHED_RR</B> (real-time,
round-robin) or <B>SCHED_FIFO</B> (real-time, first-in first-out).
</P>
<P><B>Pthreads-w32</B> only supports <B>SCHED_OTHER</B> - attempting
to set one of the other policies will return an error ENOTSUP.</P>
<P>Default value: <B>SCHED_OTHER</B>.
</P>
<P><B>Pthreads-w32</B> only supports <B>SCHED_OTHER</B> - attempting
to set one of the other policies will return an error ENOTSUP.</P>
<P>The scheduling policy of a thread can be changed after creation
with <A HREF="pthread_setschedparam.html"><B>pthread_setschedparam</B>(3)</A>
.
</P>
<H3><A HREF="#toc5" NAME="sect5">schedparam</A></H3>
<P>Contain the scheduling parameters (essentially, the scheduling
priority) for the thread.</P>
<P><B>Pthreads-w32</B> supports the priority levels defined by the
Windows system it is running on. Under Windows, thread priorities are
relative to the process priority class, which must be set via the
Windows W32 API.</P>
<P>Default value: priority is 0 (Win32 level <B>THREAD_PRIORITY_NORMAL</B>).
</P>
<P>The scheduling priority of a thread can be changed after creation
with <A HREF="pthread_setschedparam.html"><B>pthread_setschedparam</B>(3)</A>
.
</P>
<H3><A HREF="#toc6" NAME="sect6">inheritsched</A></H3>
<P>Indicate whether the scheduling policy and scheduling parameters
for the newly created thread are determined by the values of the
<I>schedpolicy</I> and <I>schedparam</I> attributes (value
<B>PTHREAD_EXPLICIT_SCHED</B>) or are inherited from the parent
thread (value <B>PTHREAD_INHERIT_SCHED</B>).
</P>
<P>Default value: <B>PTHREAD_EXPLICIT_SCHED</B>.
</P>
<H3><A HREF="#toc7" NAME="sect7">scope</A></H3>
<P>Define the scheduling contention scope for the created thread. The
only value supported in the <B>Pthreads-w32</B> implementation is
<B>PTHREAD_SCOPE_SYSTEM</B>, meaning that the threads contend for CPU
time with all processes running on the machine. The other value
specified by the standard, <B>PTHREAD_SCOPE_PROCESS</B>, means that
scheduling contention occurs only between the threads of the running
process.</P>
<P><B>Pthreads-w32</B> only supports <B>PTHREAD_SCOPE_SYSTEM</B>.</P>
<P>Default value: <B>PTHREAD_SCOPE_SYSTEM</B>.
</P>
<H2><A HREF="#toc8" NAME="sect8">Return Value</A></H2>
<P>All functions return 0 on success and a non-zero error code on
error. On success, the <B>pthread_attr_get</B><I>attrname</I>
functions also store the current value of the attribute <I>attrname</I>
in the location pointed to by their second argument.
</P>
<H2><A HREF="#toc9" NAME="sect9">Errors</A></H2>

<P>The specification of the <I>stackaddr</I> attribute presents
several ambiguities that make portable use of these interfaces
impossible. The description of the single address parameter as a
&quot;stack&quot; does not specify a particular relationship between
the address and the &quot;stack&quot; implied by that address. For
example, the address may be taken as the low memory address of a
buffer intended for use as a stack, or it may be taken as the address
to be used as the initial stack pointer register value for the new
thread. These two are not the same except for a machine on which the
stack grows &quot;up&quot; from low memory to high, and on which a
&quot;push&quot; operation first stores the value in memory and then
increments the stack pointer register. Further, on a machine where
the stack grows &quot;down&quot; from high memory to low,
interpretation of the address as the &quot;low memory&quot; address
requires a determination of the intended size of the stack.
IEEE&nbsp;Std&nbsp;1003.1-2001 has introduced the new interfaces
<A HREF="pthread_attr_setstack.html"><B>pthread_attr_setstack</B>(3)</A>
and <A HREF="pthread_attr_getstack.html"><B>pthread_attr_getstack</B>(3)</A>

</P>
<H2><A HREF="#toc2" NAME="sect2">Description</A></H2>
<P>The <B>pthread_barrier_wait</B> function shall synchronize
participating threads at the barrier referenced by <I>barrier</I>.
The calling thread shall block until the required number of threads
have called <B>pthread_barrier_wait</B> specifying the barrier.
</P>
<P>When the required number of threads have called
<B>pthread_barrier_wait</B> specifying the barrier, the constant
<B>PTHREAD_BARRIER_SERIAL_THREAD</B> shall be returned to one
unspecified thread and zero shall be returned to each of the
remaining threads. At this point, the barrier shall be reset to the
state it had as a result of the most recent <A HREF="pthread_barrier_init.html"><B>pthread_barrier_init</B>(3)</A>
function that referenced it.
</P>
<P>The constant <B>PTHREAD_BARRIER_SERIAL_THREAD</B> is defined in
<I>&lt;pthread.h&gt;</I> and its value shall be distinct from any
other value returned by <B>pthread_barrier_wait</B> .
</P>
<P>The results are undefined if this function is called with an
uninitialized barrier.
</P>
<P>If a signal is delivered to a thread blocked on a barrier, upon
return from the signal handler the thread shall resume waiting at the
barrier if the barrier wait has not completed (that is, if the
required number of threads have not arrived at the barrier during the
execution of the signal handler); otherwise, the thread shall
continue as normal from the completed barrier wait. Until the thread
in the signal handler returns from it, it is unspecified whether
other threads may proceed past the barrier once they have all reached
it.
</P>
<P>A thread that has blocked on a barrier shall not prevent any
unblocked thread that is eligible to use the same processing
resources from eventually making forward progress in its execution.
Eligibility for processing resources shall be determined by the
scheduling policy.
</P>
<H2><A HREF="#toc3" NAME="sect3">Return Value</A></H2>
<P>Upon successful completion, the <B>pthread_barrier_wait</B>
function shall return <B>PTHREAD_BARRIER_SERIAL_THREAD</B> for a
single (arbitrary) thread synchronized at the barrier and zero for
each of the other threads. Otherwise, an error number shall be
returned to indicate the error.

<P>Cancellation is the mechanism by which a thread can terminate the
execution of another thread. More precisely, a thread can send a
cancellation request to another thread. Depending on its settings,
the target thread can then either ignore the request, honor it
immediately, or defer it until it reaches a cancellation point.
</P>
<P>When a thread eventually honors a cancellation request, it
performs as if <B>pthread_exit(PTHREAD_CANCELED)</B> has been called
at that point: all cleanup handlers are executed in reverse order,
destructor functions for thread-specific data are called, and finally
the thread stops executing with the return value <B>PTHREAD_CANCELED</B>.
See <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A> for more
information.
</P>
<P><B>pthread_cancel</B> sends a cancellation request to the thread
denoted by the <I>thread</I> argument.
</P>
<P><B>pthread_setcancelstate</B> changes the cancellation state for
the calling thread -- that is, whether cancellation requests are
ignored or not. The <I>state</I> argument is the new cancellation
state: either <B>PTHREAD_CANCEL_ENABLE</B> to enable cancellation, or
<B>PTHREAD_CANCEL_DISABLE</B> to disable cancellation (cancellation
requests are ignored). If <I>oldstate</I> is not <B>NULL</B>, the
previous cancellation state is stored in the location pointed to by
<I>oldstate</I>, and can thus be restored later by another call to
<B>pthread_setcancelstate</B>.
</P>
<P><B>pthread_setcanceltype</B> changes the type of responses to
cancellation requests for the calling thread: asynchronous
(immediate) or deferred. The <I>type</I> argument is the new
cancellation type: either <B>PTHREAD_CANCEL_ASYNCHRONOUS</B> to
cancel the calling thread as soon as the cancellation request is
received, or <B>PTHREAD_CANCEL_DEFERRED</B> to keep the cancellation
request pending until the next cancellation point. If <I>oldtype</I>
is not <B>NULL</B>, the previous cancellation state is stored in the
location pointed to by <I>oldtype</I>, and can thus be restored later
by another call to <B>pthread_setcanceltype</B>.
</P>
<P><B>Pthreads-w32</B> provides two levels of support for
<B>PTHREAD_CANCEL_ASYNCHRONOUS</B>: full and partial. Full support
requires an additional DLL and driver be installed on the Windows
system (see the See Also section below) that allows blocked threads
to be cancelled immediately. Partial support means that the target
thread will not cancel until it resumes execution naturally. Partial
support is provided if either the DLL or the driver are not
automatically detected by the pthreads-w32 library at run-time.</P>
<P>Threads are always created by <A HREF="pthread_create.html"><B>pthread_create</B>(3)</A>
with cancellation enabled and deferred. That is, the initial
cancellation state is <B>PTHREAD_CANCEL_ENABLE</B> and the initial
type is <B>PTHREAD_CANCEL_DEFERRED</B>.
</P>
<P>Cancellation points are those points in the program execution
where a test for pending cancellation requests is performed and
cancellation is executed if positive. The following POSIX threads
functions are cancellation points:

<P><B>Pthreads-w32</B> provides two functions to enable additional

Win32 HANDLEs:</P>
<P><A HREF="pthreadCancelableWait.html">pthreadCancelableWait()</A>
<BR><A HREF="pthreadCancelableTimedWait.html">pthreadCancelableTimedWait()</A></P>
<P>All other POSIX threads functions are guaranteed not to be
cancellation points. That is, they never perform cancellation in
deferred cancellation mode.

<P><B>pthread_testcancel</B> does nothing except testing for pending
cancellation and executing it. Its purpose is to introduce explicit
checks for cancellation in long sequences of code that do not call

<P>POSIX specifies that a number of system calls (basically, all
system calls that may block, such as <A HREF="read.html"><B>read</B>(2)</A>
, <A HREF="write.html"><B>write</B>(2)</A> , <A HREF="wait.html"><B>wait</B>(2)</A>
, etc.) and library functions that may call these system calls (e.g.
<A HREF="fprintf.html"><B>fprintf</B>(3)</A> ) are cancellation
points. <B>Pthreads-win32</B> is not integrated enough with the C
library to implement this, and thus none of the C library functions
is a cancellation point.
</P>
<P>A workaround for these calls is to temporarily switch to
asynchronous cancellation (assuming full asynchronous cancellation
support is installed). So, checking for cancellation during a <B>read</B>
system call, for instance, can be achieved as follows:

<P>Cleanup handlers are functions that get called when a thread
terminates, either by calling <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A>
or because of cancellation. Cleanup handlers are installed and
removed following a stack-like discipline.
</P>
<P>The purpose of cleanup handlers is to free the resources that a
thread may hold at the time it terminates. In particular, if a thread
exits or is cancelled while it owns a locked mutex, the mutex will
remain locked forever and prevent other threads from executing
normally. The best way to avoid this is, just before locking the
mutex, to install a cleanup handler whose effect is to unlock the
mutex. Cleanup handlers can be used similarly to free blocks
allocated with <A HREF="malloc.html"><B>malloc</B>(3)</A> or close
file descriptors on thread termination.
</P>
<P><B>pthread_cleanup_push</B> installs the <I>routine</I> function
with argument <I>arg</I> as a cleanup handler. From this point on to
the matching <B>pthread_cleanup_pop</B>, the function <I>routine</I>
will be called with arguments <I>arg</I> when the thread terminates,
either through <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A>
or by cancellation. If several cleanup handlers are active at that
point, they are called in LIFO order: the most recently installed
handler is called first.
</P>
<P><B>pthread_cleanup_pop</B> removes the most recently installed
cleanup handler. If the <I>execute</I> argument is not 0, it also
executes the handler, by calling the <I>routine</I> function with
arguments <I>arg</I>. If the <I>execute</I> argument is 0, the
handler is only removed but not executed.
</P>
<P>Matching pairs of <B>pthread_cleanup_push</B> and
<B>pthread_cleanup_pop</B> must occur in the same function, at the
same level of block nesting. Actually, <B>pthread_cleanup_push</B>
and <B>pthread_cleanup_pop</B> are macros, and the expansion of
<B>pthread_cleanup_push</B> introduces an open brace <B>{</B> with
the matching closing brace <B>}</B> being introduced by the expansion
of the matching <B>pthread_cleanup_pop</B>.

<P>A condition (short for ‘‘condition variable’’) is a
synchronization device that allows threads to suspend execution and
relinquish the processors until some predicate on shared data is
satisfied. The basic operations on conditions are: signal the
condition (when the predicate becomes true), and wait for the
condition, suspending the thread execution until another thread
signals the condition.
</P>
<P>A condition variable must always be associated with a mutex, to
avoid the race condition where a thread prepares to wait on a
condition variable and another thread signals the condition just
before the first thread actually waits on it.
</P>
<P><B>pthread_cond_init</B> initializes the condition variable <I>cond</I>,
using the condition attributes specified in <I>cond_attr</I>, or
default attributes if <I>cond_attr</I> is <B>NULL</B>.
</P>
<P>Variables of type <B>pthread_cond_t</B> can also be initialized
statically, using the constant <B>PTHREAD_COND_INITIALIZER</B>. In
the <B>Pthreads-w32</B> implementation, an application should still
call <B>pthread_cond_destroy</B> at some point to ensure that any
resources consumed by the condition variable are released.</P>
<P><B>pthread_cond_signal</B> restarts one of the threads that are
waiting on the condition variable <I>cond</I>. If no threads are
waiting on <I>cond</I>, nothing happens. If several threads are
waiting on <I>cond</I>, exactly one is restarted, but it is not
specified which.
</P>
<P><B>pthread_cond_broadcast</B> restarts all the threads that are
waiting on the condition variable <I>cond</I>. Nothing happens if no
threads are waiting on <I>cond</I>.
</P>
<P><B>pthread_cond_wait</B> atomically unlocks the <I>mutex</I> (as
per <B>pthread_unlock_mutex</B>) and waits for the condition variable
<I>cond</I> to be signalled. The thread execution is suspended and
does not consume any CPU time until the condition variable is
signalled. The <I>mutex</I> must be locked by the calling thread on
entrance to <B>pthread_cond_wait</B>. Before returning to the calling
thread, <B>pthread_cond_wait</B> re-acquires <I>mutex</I> (as per
<B>pthread_lock_mutex</B>).
</P>
<P>Unlocking the mutex and suspending on the condition variable is
done atomically. Thus, if all threads always acquire the mutex before
signalling the condition, this guarantees that the condition cannot
be signalled (and thus ignored) between the time a thread locks the
mutex and the time it waits on the condition variable.
</P>
<P><B>pthread_cond_timedwait</B> atomically unlocks <I>mutex</I> and
waits on <I>cond</I>, as <B>pthread_cond_wait</B> does, but it also
bounds the duration of the wait. If <I>cond</I> has not been
signalled within the amount of time specified by <I>abstime</I>, the
mutex <I>mutex</I> is re-acquired and <B>pthread_cond_timedwait</B>
returns the error <B>ETIMEDOUT</B>. The <I>abstime</I> parameter
specifies an absolute time, with the same origin as <A HREF="time.html"><B>time</B>(2)</A>
and <A HREF="gettimeofday.html"><B>gettimeofday</B>(2)</A>.
</P>
<P><B>pthread_cond_destroy</B> destroys a condition variable, freeing
the resources it might hold. No threads must be waiting on the
condition variable on entrance to <B>pthread_cond_destroy</B>.</P>
<H2><A HREF="#toc3" NAME="sect3">Cancellation</A></H2>
<P><B>pthread_cond_wait</B> and <B>pthread_cond_timedwait</B> are
cancellation points. If a thread is cancelled while suspended in one
of these functions, the thread immediately resumes execution, then
locks again the <I>mutex</I> argument to <B>pthread_cond_wait</B> and
<B>pthread_cond_timedwait</B>, and finally executes the cancellation.
Consequently, cleanup handlers are assured that <I>mutex</I> is

the specified interval. The routine will not return before the end of
the period is reached, but may return an arbitrary amount of time

priorities, and system timer granularity.</P>

<H2><A HREF="#toc2" NAME="sect2">Description</A></H2>
<P><B>pthread_detach</B> puts the thread <I>th</I> in the detached
state. This guarantees that the resources consumed by <I>th</I> will
be freed immediately when <I>th</I> terminates. However, this
prevents other threads from synchronizing on the termination of <I>th</I>
using <B>pthread_join</B>. If, when <B>pthread_detach</B> is called,
<I>th</I> has already terminated, all of <I>th</I>'s remaining
resources will be freed.</P>
<P>A thread can be created initially in the detached state, using the
<B>detachstate</B> attribute to <A HREF="pthread_create.html"><B>pthread_create</B>(3)</A>
. In contrast, <B>pthread_detach</B> applies to threads created in
the joinable state, and which need to be put in the detached state
later.
</P>
<P>After <B>pthread_detach</B> completes, subsequent attempts to
perform <B>pthread_join</B> on <I>th</I> will fail. If another thread
is already joining the thread <I>th</I> at the time <B>pthread_detach</B>
is called, <I>th</I> will be detached and <B>pthread_join</B> will
eventually return when <I>th</I> terminates but may not return with
<I>th</I>'s correct return code.

<b>pthread_exit</b> terminates the

for the calling thread with <a href='file:pthread_cleanup_push.html'><b>pthread_cleanup_push</b>(3)</a>
are executed in reverse
order (the most recently pushed handler is executed first). Finalization
functions for thread-specific data are then called for all keys that have

).
Finally, execution of the calling thread is stopped.
<p> The <i>retval</i> argument
is the return value of the thread. It can be consulted from another thread
using <a href='file:pthread_join.html'><b>pthread_join</b>(3)</a>

<H2><A HREF="#toc2" NAME="sect2">Description</A></H2>
<P>Programs often need global or static variables that have different
values in different threads. Since threads share one memory space,
this cannot be achieved with regular variables. Thread-specific data
is the POSIX threads answer to this need.
</P>
<P>Each thread possesses a private memory block, the thread-specific
data area, or TSD area for short. This area is indexed by TSD keys.
The TSD area associates values of type <B>void *</B> to TSD keys. TSD
keys are common to all threads, but the value associated with a given
TSD key can be different in each thread.
</P>
<P>For concreteness, the TSD areas can be viewed as arrays of <B>void
*</B> pointers, TSD keys as integer indices into these arrays, and
the value of a TSD key as the value of the corresponding array
element in the calling thread.
</P>
<P>When a thread is created, its TSD area initially associates <B>NULL</B>
with all keys.
</P>
<P><B>pthread_key_create</B> allocates a new TSD key. The key is
stored in the location pointed to by <I>key</I>. There is a limit of
<B>PTHREAD_KEYS_MAX</B> on the number of keys allocated at a given
time. The value initially associated with the returned key is <B>NULL</B>
in all currently executing threads.
</P>
<P>The <I>destr_function</I> argument, if not <B>NULL</B>, specifies
a destructor function associated with the key. When a thread
terminates via <B>pthread_exit</B> or by cancellation, <I>destr_function</I>
is called with arguments the value associated with the key in that
thread. The <I>destr_function</I> is not called if that value is <B>NULL</B><SPAN STYLE="font-weight: medium">
or the key has been deleted</SPAN>. The order in which destructor
functions are called at thread termination time is unspecified.
</P>
<P>Before the destructor function is called, the <B>NULL</B> value is
associated with the key in the current thread. A destructor function
might, however, re-associate non- <B>NULL</B> values to that key or
some other key. To deal with this, if after all the destructors have
been called for all non- <B>NULL</B> values, there are still some
non- <B>NULL</B> values with associated destructors, then the process
is repeated.</P>
<P><B>pthread_key_delete</B> deallocates a TSD key. It does not check
whether non- <B>NULL</B> values are associated with that key in the
currently executing threads, nor call the destructor function
associated with the key.
</P>
<P><B>pthread_setspecific</B> changes the value associated with <I>key</I>
in the calling thread, storing the given <I>pointer</I> instead.
</P>
<P><B>pthread_getspecific</B> returns the value currently associated
with <I>key</I> in the calling thread.
</P>
<P>The routines <B>pthread_setspecific</B>, <B>pthread_getspecific</B>,
and <B>pthread_key_delete</B> can be called from <I>destr_function</I>
targeting any valid key including the key on which <I>destr_function</I>
is currently operating. If <B>pthread_getspecific</B> is called on
the key whose thread specific data is being destroyed, the value NULL
is returned, unless <B>pthread_setspecific</B> was called previously
on that key from within <I>destr_function</I> to set the value to
non-NULL. For some implementations the effect of calling
<B>pthread_setspecific</B> from within <I>destr_function</I> can be
either memory leakage or infinite loops if <I>destr_function</I> has
already been called at least <B>PTHREAD_DESTRUCTOR_ITERATIONS</B>
times.</P>
<P STYLE="font-weight: medium"><B>Pthreads-w32</B> stops running key
<I>destr_function</I> routines after <B>PTHREAD_DESTRUCTOR_ITERATIONS</B>
iterations, even if some non- <B>NULL</B> values with associated

from within <I>destr_function</I>, that memory may not be reclaimed

If <I>oldmask</I> is not <B>NULL</B>, the previous signal mask is
stored in the location pointed to by <I>oldmask</I>. <B>Pthreads-w32</B>

<I>how</I> is <B>SIG_UNBLOCK</B>, the signals specified to <I>newmask</I>
are removed from the current signal mask.

<P>Recall that signal masks are set on a per-thread basis, but signal

<P><B>pthread_kill</B> send signal number <I>signo</I> to the thread

return an error if <I>thread</I> is not valid.</P>
<P><B>sigwait</B> suspends the calling thread until one of the
signals in <I>set</I> is delivered to the calling thread. It then
stores the number of the signal received in the location pointed to
by <I>sig</I> and returns. The signals in <I>set</I> must be blocked
and not ignored on entrance to <B>sigwait</B>. If the delivered
signal has a signal handler function attached, that function is <I>not</I>
called. <B>Pthreads-w32</B> implements this function as a

<H2><A HREF="#toc8" NAME="sect8">Notes</A></H2>
<P>In any implementation, for <B>sigwait</B> to work reliably, the
signals being waited for must be blocked in all threads, not only in
the calling thread, since otherwise the POSIX semantics for signal
delivery do not guarantee that it’s the thread doing the <B>sigwait</B>
that will receive the signal. The best way to achieve this is to
block those signals before any threads are created, and never unblock
them in the program other than by calling <B>sigwait</B>. This works
because all threads inherit their initial sigmask from their creating
thread.</P>
<H2><A HREF="#toc9" NAME="sect9">Bugs</A></H2>
<P><B>Pthreads-w32</B> does not implement signals yet and so these
routines have almost no use except to prevent the compiler or linker
from complaining. <B>pthread_kill</B> is useful in determining if the
thread is a valid thread, but since many threads implementations
reuse thread IDs, the valid thread may no longer be the thread you
think it is, and so this method of determining thread validity is not
portable, and very risky. <B>Pthreads-w32</B> from version 1.0.0
onwards implements pseudo-unique thread IDs, so applications that use
this technique (but really shouldn't) have some protection.</P>

<P>A mutex is a MUTual EXclusion device, and is useful for protecting
shared data structures from concurrent modifications, and
implementing critical sections and monitors.
</P>
<P>A mutex has two possible states: unlocked (not owned by any
thread), and locked (owned by one thread). A mutex can never be owned
by two different threads simultaneously. A thread attempting to lock
a mutex that is already locked by another thread is suspended until
the owning thread unlocks the mutex first.
</P>
<P><B>pthread_mutex_init</B> initializes the mutex object pointed to
by <I>mutex</I> according to the mutex attributes specified in
<I>mutexattr</I>. If <I>mutexattr</I> is <B>NULL</B>, default
attributes are used instead.
</P>
<P>The type of a mutex determines whether it can be locked again by a
thread that already owns it. The default type is “normal”. See
<A HREF="pthread_mutexattr_init.html"><B>pthread_mutexattr_init</B>(3)</A>
for more information on mutex attributes.
</P>
<P>Variables of type <B>pthread_mutex_t</B> can also be initialized
statically, using the constants <B>PTHREAD_MUTEX_INITIALIZER</B> (for
normal “fast” mutexes), <B>PTHREAD_RECURSIVE_MUTEX_INITIALIZER</B>
(for recursive mutexes), and <B>PTHREAD_ERRORCHECK_MUTEX_INITIALIZER</B>
(for error checking mutexes). <SPAN STYLE="font-weight: normal">In
the </SPAN><B>Pthreads-w32</B> <SPAN STYLE="font-weight: normal">implementation,
an application should still call </SPAN><B>pthread_mutex_destroy</B>
<SPAN STYLE="font-weight: normal">at some point to ensure that any
resources consumed by the mutex are released.</SPAN></P>
<P><SPAN STYLE="font-weight: normal">Any mutex type can be
initialized as a </SPAN><B>robust mutex</B><SPAN STYLE="font-weight: normal">.

<SPAN STYLE="font-weight: normal">below.</SPAN></P>
<P><B>pthread_mutex_lock</B> locks the given mutex. If the mutex is
currently unlocked, it becomes locked and owned by the calling
thread, and <B>pthread_mutex_lock</B> returns immediately. If the
mutex is already locked by another thread, <B>pthread_mutex_lock</B>
suspends the calling thread until the mutex is unlocked.</P>
<P>If the mutex is already locked by the calling thread, the behavior
of <B>pthread_mutex_lock</B> depends on the type of the mutex. If the
mutex is of the “normal” type, the calling thread is suspended
until the mutex is unlocked, thus effectively causing the calling
thread to deadlock. If the mutex is of the ‘‘error checking’’
type, <B>pthread_mutex_lock</B> returns immediately with the error
code <B>EDEADLK</B>. If the mutex is of the ‘‘recursive’’
type, <B>pthread_mutex_lock</B> succeeds and returns immediately,
recording the number of times the calling thread has locked the
mutex. An equal number of <B>pthread_mutex_unlock</B> operations must
be performed before the mutex returns to the unlocked state.
</P>
<P><B>pthread_mutex_trylock</B> behaves identically to
<B>pthread_mutex_lock</B>, except that it does not block the calling
thread if the mutex is already locked by another thread (or by the
calling thread in the case of a “normal” or “<SPAN STYLE="font-style: normal">errorcheck</SPAN>”
mutex). Instead, <B>pthread_mutex_trylock</B> returns immediately
with the error code <B>EBUSY</B>.
</P>
<P><B>pthread_mutex_timedlock</B> behaves identically to
<B>pthread_mutex_lock</B>, except that if it cannot acquire the lock
before the <I>abs_timeout</I> time, the call returns with the error
code <B>ETIMEDOUT</B>. If the mutex can be locked immediately it is,
and the <B>abs_timeout</B> parameter is ignored.</P>
<P><B>pthread_mutex_consistent</B> may only be called for
<B>PTHREAD_MUTEX_ROBUST</B> mutexes. It simply marks the mutex as
consistent. See <I><U>Robust Mutexes</U></I> below.</P>
<P><B>pthread_mutex_unlock</B> unlocks the given mutex. The mutex is
assumed to be locked and owned by the calling thread on entrance to
<B>pthread_mutex_unlock</B>. If the mutex is of the “normal”
type, <B>pthread_mutex_unlock</B> always returns it to the unlocked
state. If it is of the ‘‘recursive’’ type, it decrements the
locking count of the mutex (number of <B>pthread_mutex_lock</B>
operations performed on it by the calling thread), and only when this
count reaches zero is the mutex actually unlocked. In <B>Pthreads-win32</B>,
non-robust normal or default mutex types do not check the owner of
the mutex. For all types of robust mutexes the owner is checked and
an error code is returned if the calling thread does not own the
mutex.</P>
<P>On ‘‘error checking’’ mutexes, <B>pthread_mutex_unlock</B>
actually checks at run-time that the mutex is locked on entrance, and
that it was locked by the same thread that is now calling
<B>pthread_mutex_unlock</B>. If these conditions are not met, an
error code is returned and the mutex remains unchanged. ‘‘Normal’’
[non-robust] mutexes perform no such checks, thus allowing a locked
mutex to be unlocked by a thread other than its owner. This is
non-portable behavior and is not meant to be used as a feature.</P>
<P><B>pthread_mutex_destroy</B> destroys a mutex object, freeing the
resources it might hold. The mutex must be unlocked on entrance.</P>
<H2 CLASS="western"><A HREF="#toc10" NAME="sect10">Robust Mutexes</A></H2>
<P>If the mutex is <B>PTHREAD_MUTEX_ROBUST</B> and the owning thread
terminates without unlocking the mutex the implementation will wake
one waiting thread, if any. The next thread to acquire the mutex will
receive the error code <B>EOWNERDEAD</B><SPAN STYLE="font-weight: normal">,
in which case that thread should if possible ensure that the state
protected by the mutex is consistent and then call
</SPAN><B>pthread_mutex_consistent</B> <SPAN STYLE="font-weight: normal">before
unlocking. The mutex may then be used normally from then on.</SPAN></P>
<P><SPAN STYLE="font-weight: normal">If the thread cannot recover the
state then it must call </SPAN><B>pthread_mutex_unlock</B><SPAN STYLE="font-weight: normal">
without calling </SPAN><B>pthread_mutex_consistent</B><SPAN STYLE="font-weight: normal">.
This will mark the mutex as unusable and wake all currently waiting
threads with the return code </SPAN><B>ENOTRECOVERABLE</B><SPAN STYLE="font-weight: normal">.
The error indicates that the mutex is no longer usable and any
threads that receive this error code from any lock operation have not
acquired the mutex. The mutex can be made consistent by calling
</SPAN><B>pthread_mutex_destroy</B> <SPAN STYLE="font-weight: normal">to
uninitialize the mutex, and calling </SPAN><B>pthread_mutex_int</B>
<SPAN STYLE="font-weight: normal">to reinitialize the mutex. However,
the state that was protected by the mutex remains inconsistent and
some form of application recovery is required.</SPAN></P>
<P><SPAN STYLE="font-weight: normal">If a thread that receives the
</SPAN><B>EOWNERDEAD</B> <SPAN STYLE="font-weight: normal">error code
itself terminates without unlocking the mutex then this behaviour
repeats for the next acquiring thread.</SPAN></P>
<P><SPAN STYLE="font-weight: normal">Applications must ensure that
they check the return values from all calls targeting robust mutexes.</SPAN></P>
<P STYLE="font-weight: normal">Robust mutexes are slower because they
require some additional overhead, however they are not very much
slower than the non-robust recursive type.</P>
<H2 CLASS="western"><A HREF="#toc3" NAME="sect3">Cancellation</A></H2>
<P>None of the mutex functions is a cancellation point, not even
<B>pthread_mutex_lock</B>, in spite of the fact that it can suspend a
thread for arbitrary durations. This way, the status of mutexes at
cancellation points is predictable, allowing cancellation handlers to
unlock precisely those mutexes that need to be unlocked before the
thread stops executing. Consequently, threads using deferred
cancellation should never hold a mutex for extended periods of time.
</P>
<H2 CLASS="western"><A HREF="#toc4" NAME="sect4">Async-signal Safety</A></H2>
<P>The mutex functions are not async-signal safe. What this means is
that they should not be called from a signal handler. In particular,
calling <B>pthread_mutex_lock</B> or <B>pthread_mutex_unlock</B> from
a signal handler may deadlock the calling thread.
</P>
<H2 CLASS="western"><A HREF="#toc5" NAME="sect5">Return Value</A></H2>
<P><B>pthread_mutex_init</B> always returns 0. The other mutex
functions return 0 on success and a non-zero error code on error.
