Allocate a zero-initialized array.
Defined in <SDL3/SDL_stdinc.h>
void * SDL_calloc(size_t nmemb, size_t size);| size_t | nmemb | the number of elements in the array. |
| size_t | size | the size of each element of the array. |
(void *) Returns a pointer to the allocated array, or NULL if allocation failed.
The memory returned by this function must be freed with SDL_free().
If either of nmemb or size is 0, they will both be set to 1.
If the allocation is successful, the returned pointer is guaranteed to be aligned to either the fundamental alignment (alignof(max_align_t) in C11 and later) or 2 * sizeof(void *), whichever is smaller. Use SDL_aligned_alloc_zero() if you need to allocate memory aligned to an alignment greater than this guarantee.
It is safe to call this function from any thread.
This function is available since SDL 3.2.0.
