gzdopen does not close fd if it fails.
gzdopen does not close fd if it fails. If you are using fileno() to get the
file descriptor from a FILE *, then you will have to use dup() to avoid
double-close()ing the file descriptor. Both gzclose() and fclose() will
close the associated file descriptor, so they need to have different file
descriptors.
gzdopen returns NULL if there was insufficient memory to allocate the
gzFile state, if an invalid mode was specified (an 'r', 'w', or 'a' was not

concatenated in the input file, and will all be decompressed by gzread().
If something other than a gzip stream is encountered after a gzip stream,
that remaining trailing garbage is ignored (and no error is returned).
gzread can be used to read a gzip file that is being concurrently written.
Upon reaching the end of the input, gzread will return with the available
data. If the error code returned by gzerror is Z_OK or Z_BUF_ERROR, then
gzclearerr can be used to clear the end of file indicator in order to permit
gzread to be tried again. Z_OK indicates that a gzip stream was completed
on the last gzread. Z_BUF_ERROR indicates that the input file ended in the
middle of a gzip stream. Note that gzread does not return -1 in the event
of an incomplete gzip stream. This error is deferred until gzclose(), which
will return Z_BUF_ERROR if the last gzread ended in the middle of a gzip
stream. Alternatively, gzerror can be used before gzclose to detect this
case.
gzread returns the number of uncompressed bytes actually read, less than
len for end of file, or -1 for error.

/* ioapi.h -- IO base function header for compress/uncompress .zip
files using zlib + zip or unzip API
part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
Version 1.01h, December 28th, 2009
Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
Changes
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
More if/def section may be needed to support other platforms
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
(but you should use iowin32.c for windows instead)

// skipset.h -- set operations using a skiplist
// Copyright (C) 2024 Mark Adler
// See MiniZip_info.txt for the license.
// This implements a skiplist set, i.e. just keys, no data, with ~O(log n) time
// insert and search operations. The application defines the type of a key, and
// provides a function to compare two keys.
// This header is not definitions of functions found in another source file --
// it creates the set functions, with the application's key type, right where
// the #include is. Before this header is #included, these must be defined:
//
// 1. A macro or typedef for set_key_t, the type of a key.
// 2. A macro or function set_cmp(a, b) to compare two keys. The return values
// are < 0 for a < b, 0 for a == b, and > 0 for a > b.
// 3. A macro or function set_drop(s, k) to release the key k's resources, if
// any, when doing a set_end() or set_clear(). s is a pointer to the set
// that key is in, for use with set_free() if desired.
//
// Example usage:
//
// typedef int set_key_t;
// #define set_cmp(a, b) ((a) < (b) ? -1 : (a) == (b) ? 0 : 1)
// #define set_drop(s, k)
// #include "skipset.h"
//
// int test(void) { // return 0: good, 1: bad, -1: out of memory
// set_t set;
// if (setjmp(set.env))
// return -1;
// set_start(&set);
// set_insert(&set, 2);
// set_insert(&set, 1);
// set_insert(&set, 7);
// int bad = !set_found(&set, 2);
// bad = bad || set_found(&set, 5);
// set_end(&set);
// return bad;
// }
//
// Interface summary (see more details below):
// - set_t is the type of the set being operated on (a set_t pointer is passed)
// - set_start() initializes a new, empty set (initialize set.env first)
// - set_insert() inserts a new key into the set, or not if it's already there
// - set_found() determines whether or not a key is in the set
// - set_end() ends the use of the set, freeing all memory
// - set_clear() empties the set, equivalent to set_end() and then set_start()
// - set_ok() checks if set appears to be usable, i.e. started and not ended
//
// Auxiliary functions available to the application:
// - set_alloc() allocates memory with optional tracking (#define SET_TRACK)
// - set_free() deallocates memory allocated by set_alloc()
// - set_rand() returns 32 random bits (seeded by set_start())
