(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_arraysize

The number of elements in an array.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

#define SDL_arraysize(array) (sizeof(array)/sizeof(array[0]))

Remarks

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.

Version

This macro is available since SDL 3.1.3.
