Mark Adler	7dd6aa7245	Fix bug when gzungetc() is used immediately after gzopen().	1 year ago
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.	2 years ago
Mark Adler	9331fecc10	Remove redundant check in gz_look().	2 years ago
Mark Adler	21767c654d	zlib 1.2.12	3 years ago
Mark Adler	793ad7f559	Avoid some conversion warnings in gzread.c and gzwrite.c.	8 years ago
Mark Adler	2fa463bacf	zlib 1.2.9	8 years ago
Mark Adler	cca27e95cf	Avoid the need for ssize_t. Limit read() and write() requests to sizes that fit in an int. This allows storing the return value in an int, and avoiding the need to use or construct an ssize_t type. This is required for Microsoft C, whose _read and _write functions take an unsigned request and return an int.	8 years ago
Mark Adler	feafcfaa05	No need to check for NULL argument to free().	8 years ago
Mark Adler	44dfd831d2	Add gzfread(), duplicating the interface of fread().	8 years ago
Mark Adler	ca50ebd4df	Create z_size_t and z_ssize_t types. Normally these are set to size_t and ssize_t. But if they do not exist, then they are set to the smallest integer type that can contain a pointer. size_t is unsigned and ssize_t is signed.	8 years ago
Mark Adler	7096424f23	Clean up type conversions.	8 years ago
Mark Adler	0b16609409	zlib 1.2.7.1	12 years ago
Mark Adler	e9f0b78443	Add casts and consts to ease user conversion to C++. You would still need to run zlib2ansi on all of the *.c files.	12 years ago
Mark Adler	62d6112a79	Clean up the usage of z_const and respect const usage within zlib. This patch allows zlib to compile cleanly with the -Wcast-qual gcc warning enabled, but only if ZLIB_CONST is defined, which adds const to next_in and msg in z_stream and in the in_func prototype. A --const option is added to ./configure which adds -DZLIB_CONST to the compile flags, and adds -Wcast-qual to the compile flags when ZLIBGCCWARN is set in the environment.	13 years ago
Mark Adler	6a181356bd	Fix gzgetc undefine when Z_PREFIX set [Turk].	13 years ago
Mark Adler	d81e7213b7	Restore gzgetc_ for backward compatibility with 1.2.6.	13 years ago
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.	13 years ago
Mark Adler	94acb3c1a0	zlib 1.2.6.1	13 years ago
Mark Adler	1a4ba8cd91	Remove unnecessary gzgetc_ function.	13 years ago
Mark Adler	3d85f02a09	Restore gzgetc function for binary compatibility. Newly compiled applications will use the gzgetc macro.	13 years ago
Mark Adler	2556706d67	Document gzread() capability to read concurrently written files. Also since gzread() will no longer return an error for an incomplete gzip file, have gzclose() return an error if the last gzread() ended in the middle of a gzip stream.	13 years ago
Mark Adler	850a198ff1	Avoid use of Z_BUF_ERROR in gz* functions except for premature EOF. Z_BUF_ERROR was also being used for an unsuccessful gzungetc and for buffer lengths that didn't fit in an int. Those uses were changed to Z_DATA_ERROR in order to assure that Z_BUF_ERROR occurs only when a premature end of input occurs, indicating that gzclearerr() can be used.	13 years ago
Mark Adler	377173b57e	Fix bug in gzread.c when end-of-file is reached.	13 years ago
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.	13 years ago
Mark Adler	26a99cd895	Add a transparent write mode to gzopen() when 'T' is in the mode.	13 years ago
Mark Adler	a4f7c65374	Update copyright dates on gz* source files.	13 years ago
Mark Adler	acfc85772a	Change gzgetc() to a macro for speed (~40% speedup in testing).	13 years ago
Mark Adler	8e0d212910	Simplify gzseek() now that raw after gzip is ignored.	13 years ago
Mark Adler	5ad116abda	Allow gzread() and related to continue after gzclearerr(). Before this fix, gzread() would lose data if a premature end of file was encountered. This prevented gzread() from being used on a file that was being written concurrently. Now gzread() returns all of the data it has available before indicating a premature end of file. This also changes the error returned on a premature end of file from Z_DATA_ERROR to Z_BUF_ERROR. This allows the user to determine if the error is recoverable, which it is if Z_BUF_ERROR is returned. If a Z_DATA_ERROR is returned, then the error is not recoverable. This patch replaces the functionality of a previous patch that fixed reading through an empty gzip stream in a concatenation of gzip streams. To implement this fix, a noticeable rewrite of gzread.c was needed. The patch has the added advantage of using inflate's gzip processing instead of replicating the functionality in gzread.c. This makes the gz code a little simpler.	13 years ago
Mark Adler	a9ae24b653	Change gzread() and related to ignore junk after gzip streams. Previously the new gz* functions (introduced in 1.2.4) would read and return raw data after the last gzip stream. This is inconsistent with the behavior of gzip and the previous versions of zlib. Now when one or more gzip streams have been decoded from the file, which is then followed by data that is not a gzip stream (as detemined by not finding the magic header), then that subsequent trailing garbage is ignored, and no error is returned.	13 years ago
