Anton Khirnov	f935aca44c	av_memcpy_backptr: avoid an infinite loop for back = 0 CC:libav-stable@libav.org	12 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Mans Rullgard	4a606c830a	av_memcpy_backptr: optimise some special cases - Add special cases for offsets of 2, 3, or 4 bytes. This means the offset is always >4 in the generic case, allowing 32-bit copies to be used there. - Don't use memcpy() for sizes less than 16 bytes.

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

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
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
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

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

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

Herve W	a949360163	* Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's no need for 1 more extra byte. * Checking whether the to be allocated size is larger than INT_MAX, doesn't assure that size+16 bytes for the MEMALIGN_HACK isn't larger than INT_MAX. * malloc might return NULL. Checking for it before using that pointer seems like a good idea. Patch by Herve W.
