Functions

void av_max_alloc (size_t max)

Set the maximum size that may me allocated in one block.

void * av_malloc (size_t size)

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

void * av_realloc (void *ptr, size_t size)

Allocate or reallocate a block of memory.

void * av_realloc_f (void *ptr, size_t nelem, size_t elsize)

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().

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.

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.

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.

char * av_strdup (const char *s)

Duplicate the string s.

void av_dynarray_add (void *tab_ptr, int *nb_ptr, void *elem)

Add an element to a dynamic array.
