| * mem: add support for _aligned_malloc() as found on WindowsRonald S. Bultje2012-06-19
| | | | | | | | | | | | | | | | 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>
| * mem: Consistently return NULL for av_malloc(0)Martin Storsjö2012-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | Fix posix_memalign() usage when libavutil is compiled outside FFmpeg.Ivan Kalvachev2011-05-12
| | | | | | | | | | | | | | | | | | 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.
