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)
	Allocate a block of size bytes with alignment suitable for all memory accesses (including vectors if available on the CPU) and zero all the bytes of the block. More...

void *	av_calloc (size_t nmemb, size_t size)
	Allocate a block of nmemb * size bytes with alignment suitable for all memory accesses (including vectors if available on the CPU) and zero all the bytes of the block. More...

char *	av_strdup (const char *s)
	Duplicate the string s. More...
