Diego Biurrun	5bac2d0c30	avutil: Move memcpy_backptr() to mem.c The function is used elsewhere and does not belong with the LZO code.	12 years ago
Diego Biurrun	5532cf3178	avutil/mem: K&R formatting cosmetics	12 years ago
Martin Storsjö	620b1e7e98	mem: Don't abort on av_malloc(0) in debug mode This makes the behaviour consistent between debug and release mode. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Clément Bœsch	7c84e7d337	mem: heap memory poisoning. Enable it by default with FATE. limitation: not random, and not supported with realloc.	13 years ago
Ronald S. Bultje	be1a839ca6	mem: add support for _aligned_malloc() as found on Windows The check uses check_func_header, since this function is conditionally available depending on the targeted MSVCRT version. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Reimar Döffinger	1a65d50ee7	mem.c: fix wrong comment. Overwriting the av_malloc etc. functions is not easily possible anymore, even for systems that support overriding symbols in shared libraries in principle. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Martin Storsjö	14f063d294	mem: Consistently return NULL for av_malloc(0) Plain POSIX malloc(0) is allowed to return either NULL or a non-NULL pointer. The calling code should be ready to handle a NULL return as a correct return (instead of a failure) if the size to allocate was 0 - this makes sure the condition is handled in a consistent way across platforms. This also avoids calling posix_memalign(&ptr, 32, 0) on OS X, which returns an invalid pointer (a non-NULL pointer that causes crashes when passed to av_free). Abort in debug mode, to help track down issues related to incorrect handling of this case. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	7181c4edee	cosmetics: Remove extra newlines at EOF	13 years ago
Michael Niedermayer	5a8e994287	mem: add av_max_alloc() to limit the maximum amount that may be allocated in one piece Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Hanspeter Niederstrasser	bed04e2b03	Correct use of OSX to Mac OS X and properly format yasm providers on Mac OS X Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	fc11927890	mem: fix memalign hack av_realloc() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	5cd754bca2	Introduce av_realloc_f. av_realloc_f helps avoiding memory-leaks in typical uses of realloc. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Laurent Aimar	ccecab4a0d	Add av_calloc() helper. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a39bd458a0	mem: Trying to workaround posix_memalign() bug on OSX This patch is based on a patch by John Stebbins Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Stefano Sabatini	6b4c0be558	mem: define the MAX_MALLOC_SIZE constant and use it in place of INT_MAX This makes re-dimensionating the constant simpler, since now it is defined only in one place.	14 years ago
Ivan Kalvachev	518cdff81f	Fix posix_memalign() usage when libavutil is compiled outside FFmpeg. To use posix_memalign() "#define _XOPEN_SOURCE 600" have to be defined. FFmpeg configure defines it from the command line through config.mak, but when libavutil is used outside of FFmpeg the define is missing.

Michael Niedermayer	b47541c7a3	Change the argument of memory allocation functions from unsigned int to size_t with the next major bump in libavutil. Originally committed as revision 25871 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4ae406856f	Add --malloc-prefix to apply a prefix to malloc, free etc This makes it easy to use a replacement allocator instead of the system default one. Originally committed as revision 21509 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Patrik Kullman	a90de11dba	Check return value of posix_memalign and explicitly set pointer to NULL if it fails, patch by Patrik Kullman, patrik yes nu. Originally committed as revision 17495 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	692c315e3a	Do not #include common.h without necessity. This eliminates the need to work around common.h overriding certain system functions which are required in this header. Originally committed as revision 16776 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
