void	av_free (void *ptr)
	Free a memory block which has been allocated with av_malloc(z)() or av_realloc(). More...

void	av_freep (void *arg)
	Free a memory block which has been allocated with av_malloc(z)() or av_realloc() and set the pointer pointing to it to NULL. More...

void *	av_mallocz (size_t size)
