Rémi Denis-Courmont	6039248018	mem: fix pointer pointer aliasing violations This uses explicit memory copying to read and write pointer to pointers of arbitrary object types. This works provided that the architecture uses the same representation for all pointer types (the previous code made that assumption already anyway). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Anton Khirnov	8ddc32629a	mem: add av_strndup() for duplicating substrings	10 years ago
Anton Khirnov	cce3e0a49f	Move av_fast_{m,re}alloc from lavc to lavu.	11 years ago
Martin Storsjö	d433e1aefa	mem: Make av_strdup allocate using av_realloc This makes sure that pointers from av_strdup are reallocable, which is used in av_dict_set if the AV_DICT_APPEND flag is set. Nothing should rely on pointers from av_strdup being aligned. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	67e285ceca	mem: Handle av_reallocp(..., 0) properly Previously this did a double free (and returned an error). Reported-by: Justin Ruggles Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Martin Storsjö	fc962d4e7a	mem: Add av_realloc_array and av_reallocp_array These help avoiding overflows and simplify error handling. Signed-off-by: Martin Storsjö <martin@martin.st>	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. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
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
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
