Functions

voidav_malloc (size_t size) av_malloc_attrib av_alloc_size(1)

voidav_realloc (void *ptr, size_t size) av_alloc_size(2)
 Allocate or reallocate a block of memory.
void av_free (void *ptr)
 Free a memory block which has been allocated with av_malloc(z)() or av_realloc().
voidav_mallocz (size_t size) av_malloc_attrib av_alloc_size(1)
 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.
char * av_strdup (const char *s) av_malloc_attrib
 Duplicate the string s.
void av_freep (void *ptr)
 Free a memory block which has been allocated with av_malloc(z)() or av_realloc() and set the pointer pointing to it to NULL.
