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
Luca Barbato	3feb3d6ce4	mem: Introduce av_reallocp	11 years ago
Diego Biurrun	c3e6e8f06c	mem: Do not check unsigned values for negative size	11 years ago
Diego Biurrun	b634b36fce	mem: Improve documentation wording and spelling	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	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. 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
Alex Converse	7181c4edee	cosmetics: Remove extra newlines at EOF	13 years ago
Vitor Sessak	13dfce3d44	Increase alignment of av_malloc() as needed by AVX ASM. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Anton Khirnov	490a022d86	lavu: remove misc disabled cruft	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Clément Bœsch	dc75d6dbf2	Avoid pointless check before calling free Signed-off-by: Mans Rullgard <mans@mansr.com>	14 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
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
