SDL_arraysize - The number of elements in a static array.
Defined in SDL3/SDL_stdinc.h
#include "SDL3/SDL.h"
#define SDL_arraysize(array) (sizeof(array)/sizeof(array[0]))
This will compile but return incorrect results for a pointer to an array; it has to be an array the compiler knows the size of.
This macro looks like it double-evaluates the argument, but it does so inside of sizeof , so there are no side-effects here, as expressions do not actually run any code in these cases.
This macro is available since SDL 3.2.0.
