<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>
