Mark Adler e342bb3dae Assume no snprintf() or vsnprintf() if C89/90 in gzguts.h. 
Those functions were introduced in C99. However it is assumed that
they are there if under Windows, since Visual C claims C89/90, but
does have those functions, or variants.

Mark Adler 1382e66114 Use _POSIX_C_SOURCE in gzguts.h, instead of _POSIX_SOURCE. 2024-02-06 18:27:24 -08:00

Milan Bulat 01253ecd7e Make the existence of gz_intmax() unconditional. 
gz_intmax() is noted in zlib.map. This assures it's always there.

Mark Adler a566e156b3 Avoid compiler complaints if _TIME_BITS defined when building zlib. 
zlib does not use time_t, so _TIME_BITS is irrelevant. However it
may be defined anyway as part of a sledgehammer indiscriminately
applied to all builds.

Mark Adler e9d5486e66 Remove K&R function definitions from zlib. 
C2X has removed K&R definitions from the C function syntax.
Though the standard has not yet been approved, some high-profile
compilers are now issuing warnings when such definitions are
encountered.

Mark Adler d211ecdf02 Use underscored I/O function names for WINAPI_FAMILY. 
Suggested by E. Timothy Uy.

Mark Adler 25e4a3da55 Use _snprintf for snprinf in Microsoft C. 
More than a decade later, Microsoft C does not support the C99
standard.  It's good that _snprintf has a different name, since it
does not guarantee that the result is null terminated, as does
snprintf.  However where _snprintf is used under Microsoft C, the
destination string is assured to be long enough, so this will not
be a problem.  This occurs in two places, both in gzlib.c.  Where
sprintf functionality is needed by gzprintf, vsnprintf is used in
the case of Microsoft C.

Mark Adler a1af6e96e3 Fix gzopen_w() type and add #include for the type. 2012-03-17 21:45:01 -07:00
Mark Adler dbe0bed739 Add gzopen_w() in Windows for wide character path names. 2012-03-16 20:53:09 -07:00

Mark Adler 3f4339b61b Improve the detection of no hidden visibility attribute. 2012-02-19 23:33:10 -08:00
Mark Adler e6d2a8471b Do not use the visibility attribute if NO_VIZ defined. 2012-02-19 22:45:10 -08:00
Mark Adler a75d6ea070 Require gcc 4.0 or later on Mac OS X to use the hidden attribute. 2012-02-18 15:37:28 -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.

Mark Adler 3fb727c34d Include io.h in gzguts.h for Microsoft compilers. 2012-01-29 21:15:24 -08:00

Mark Adler b9a778a2b8 Include io.h for Turbo C / Borland C on all platforms [Truta]. 2012-01-18 19:33:02 -08:00
Mark Adler 98f5779f42 Fix gzeof() to behave just like feof() when read is not past end of file. 
Before, gzeof() would return true (accurately) when the last read request
went just up to the end of the uncompressed data.  In the analogous case,
feof() would return false, only returning true when a read request goes
past the end of the file.  This patch corrects gzeof() to behave in the
same way as feof(), as noted in the zlib.h documentation.

Mark Adler fb00fda903 Fix gzwrite.c to accommodate reduced memory zlib compilation. 
gzwrite.c had hard-coded parameters to deflateInit2() which could
contradict compile-time options for the use of less memory and fewer
code bits.  This patch suggested by Karsten Saunte fixes that.

Mark Adler 0cbad869b0 Include io.h for Turbo C / Borland C++. 2011-11-21 18:38:37 -08:00

Mark Adler 26a99cd895 Add a transparent write mode to gzopen() when 'T' is in the mode. 2011-10-02 13:34:29 -07:00
Mark Adler 00c836e325 Merge vestigial vsnprintf determination from zutil.h to gzguts.h. 
This also moves some of the same from zconf.h to gzguts.h. A new
function, gzflags(), was created to pass the compilation flags
related to vsnprintf usage back to zlibCompileFlags() in zutil.c.
In the process, various compiler configuration files were updated
to include gzflags(), as well as the new gzgetc_() function added
when the gzgetc() macro was introduced in a previous patch.
