SDL_zeroa - Clear an array’s memory to zero.

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

#define SDL_zeroa(x) SDL_memset((x), 0, sizeof((x)))

This is wrapper over SDL_memset
that handles calculating the array size, so there’s no chance of copy/paste errors, and the code is cleaner.

This requires an array, not an object, nor a pointer to an object.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
