SDL_calloc

Allocate a zero-initialized array.

Header File

Syntax

void * SDL_calloc(size_t nmemb, size_t size);

Function Parameters

size_t	nmemb	the number of elements in the array.
size_t	size	the size of each element of the array.

Return Value

(void *) Returns a pointer to the allocated array, or NULL if allocation failed.

Remarks

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.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.2.0.
