Mark Adler	6c9bd474aa	Fix type mismatch between get_crc_table() and crc_table. crc_table is made using a four-byte integer (when that can be determined). However get_crc_table() returned a pointer to an unsigned long, which could be eight bytes. This fixes that by creating a new z_crc_t type for the crc_table. This type is also used for the BYFOUR crc calculations that depend on a four-byte type. The four-byte type can now be determined by ./configure, which also solves a problem where ./configure --solo would never use BYFOUR. No the Z_U4 #define indicates that four- byte integer was found either by ./configure or by zconf.h.	2012-04-29 16:18:12 -07:00

Mark Adler	a5d803b7ef	Attempt to convert the wchar_t path in gzopen_w() for errors. The conversion to multi-byte will be locale-specific, but it's better than nothing and is only to provide more information in the error message returned by gz_error(). The conversion has no effect on what's opened.	2012-03-18 14:52:31 -07:00
Mark Adler	04afd39fcc	Fix syntax error in gzlib.c.	2012-03-18 14:25:00 -07:00

Mark Adler	8e16df2c3f	More fixes for gzopen_w(). Also need to #include <stddef.h> for zlib.h, and need to workaround the inability to use wide characters in constructed error messages with zlib's interface.	2012-03-18 09:29:44 -07:00

Christoph J. Thompson	39c7ed14ac	If using cmake with MSVC, add the source directory to the includes. modified: CMakeLists.txt	2012-03-12 22:15:16 -07:00
Christoph J. Thompson	c1e84b258c	Include version symbols for cmake builds. Add a version variable so it gets added to the pkg-config file.	2012-03-11 10:16:12 -07:00

Mark Adler	755c41dc4b	Add "x" (O_EXCL) and "e" (O_CLOEXEC) modes support to gzopen().	2012-03-03 10:27:57 -08:00

Mark Adler	dab7531ecc	Simplify test and use of gcc hidden attribute.	2012-03-03 00:20:00 -08:00
Mark Adler	2547c6c81f	Don't use library or built-in byte swaps. Using optimized byte swaps reduced portability for no real benefit, since they are in parts of the code that represent a tiny fraction of the execution time. So a simple definition of a byte swap is now used.	2012-03-03 00:03:30 -08:00
Mark Adler	513dfcc00e	Fix make_vms.com for VAX [Zinser].	2012-03-02 23:50:17 -08:00

Mark Adler	6838df9246	Test for existence of strerror. SunOS 4.1 claims that it is __STDC__, but it does not have strerror in string.h. Instead of using __STDC__, this puts a direct test for strerror in configure, and uses that information in gzguts.h.	2012-02-18 13:55:09 -08:00
Mark Adler	d1714a57c5	Replace use of memmove() with a simple copy for portability. SunOS 4.1 doesn't have memmove(), and there may be others. memcpy() should not be used for overlapping copies, so here a simple copy is implemented that works for the particular direction of the overlap, which is where the destination precedes the source.	2012-02-18 13:37:45 -08:00
Mark Adler	455adc3029	Expunge gzgetc_ from configuration files.	2012-02-13 23:34:48 -08:00
Mark Adler	eee7b9e576	Remove unnecessary include for byte swap built-in [Bosmans].	2012-02-13 23:03:36 -08:00
