av_calloc void* av_calloc(size_t nmemb, size_t size): Non-inlined equivalent of av_mallocz_array().
av_dynarray2_add
void* av_dynarray2_add(void** tab_ptr, int* nb_ptr, size_t elem_size, const(ubyte)* elem_data): Add an element of size elem_size to a dynamic array.
av_dynarray_add void av_dynarray_add(void* tab_ptr, int* nb_ptr, void* elem): Add the pointer to an element to a dynamic array.
av_dynarray_add_nofree int av_dynarray_add_nofree(void* tab_ptr, int* nb_ptr, void* elem): Add an element to a dynamic array.
av_fast_malloc void av_fast_malloc(void* ptr, uint* size, size_t min_size): Allocate a buffer, reusing the given one if large enough.
av_fast_mallocz void av_fast_mallocz(void* ptr, uint* size, size_t min_size): Allocate and clear a buffer, reusing the given one if large enough.
av_fast_realloc void* av_fast_realloc(void* ptr, uint* size, size_t min_size): Reallocate the given buffer if it is not large enough, otherwise do nothing.
av_free void av_free(void* ptr): Free a memory block which has been allocated with a function of av_malloc() or av_realloc() family.
av_freep void av_freep(void* ptr): Free a memory block which has been allocated with a function of av_malloc() or av_realloc() family, and set the pointer pointing to it to NULL.
av_malloc void* av_malloc(size_t size): Allocate a memory block with alignment suitable for all memory accesses (including vectors if available on the CPU).
av_malloc_array void* av_malloc_array(size_t nmemb, size_t size): Allocate a memory block for an array with av_malloc().
av_mallocz void* av_mallocz(size_t size): Allocate a memory block with alignment suitable for all memory accesses (including vectors if available on the CPU) and zero all the bytes of the block.
av_mallocz_array void* av_mallocz_array(size_t nmemb, size_t size): Allocate a memory block for an array with av_mallocz().
av_max_alloc void av_max_alloc(size_t max): Set the maximum size that may be allocated in one block.
av_memcpy_backptr void av_memcpy_backptr(ubyte* dst, int back, int cnt): Overlapping memcpy() implementation.
av_memdup void* av_memdup(const(void)* p, size_t size): Duplicate a buffer with av_malloc().
av_realloc void* av_realloc(void* ptr, size_t size): Allocate, reallocate, or free a block of memory.
av_realloc_array void* av_realloc_array(void* ptr, size_t nmemb, size_t size): Allocate, reallocate, or free an array.
av_realloc_f void* av_realloc_f(void* ptr, size_t nelem, size_t elsize): Allocate, reallocate, or free a block of memory.
av_reallocp int av_reallocp(void* ptr, size_t size): Allocate, reallocate, or free a block of memory through a pointer to a pointer.
av_reallocp_array int av_reallocp_array(void* ptr, size_t nmemb, size_t size): Allocate, reallocate, or free an array through a pointer to a pointer.
av_size_mult int av_size_mult(size_t a, size_t b, size_t* r): Multiply two size_t values checking for overflow.
av_strdup char* av_strdup(const(char)* s): Duplicate a string.
av_strndup char* av_strndup(const(char)* s, size_t len): Duplicate a substring of a string.
