Type Alias SDL_calloc_func 

pub type SDL_calloc_func = Option<unsafe extern "C" fn(nmemb: usize, size: usize) -> *mut c_void>;

A callback used to implement SDL_calloc().

SDL will always ensure that the passed nmemb and size are both greater than 0.

Parameter: nmemb the number of elements in the array. Parameter: size the size of each element of the array. Returns: a pointer to the allocated array, or NULL if allocation failed.

Thread Safety: It should be safe to call this callback from any thread.

Available Since: This datatype is available since SDL 3.2.0.
