Type Alias SDL_realloc_func 

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

A callback used to implement SDL_realloc().

SDL will always ensure that the passed size is greater than 0.

Parameter: mem a pointer to allocated memory to reallocate, or NULL. Parameter: size the new size of the memory. Returns: a pointer to the newly allocated memory, 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.
