NAME

SDL_calloc - Allocate a zero-initialized array.

SYNOPSIS

#include <SDL3/SDL_stdinc.h>

void * SDL_calloc(size_t nmemb, size_t size);

DESCRIPTION

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.

FUNCTION PARAMETERS

nmemb

the number of elements in the array.

size

the size of each element of the array.

RETURN VALUE

Returns a pointer to the allocated array, or NULL if allocation failed.

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
