NAME
SDL_zeroa - Clear an array's memory to zero.
HEADER FILE
Defined in SDL3/SDL_stdinc.h
SYNOPSIS
#include "SDL3/SDL.h" #define SDL_zeroa(x) SDL_memset((x), 0, sizeof((x)))
DESCRIPTION
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.
THREAD SAFETY
It is safe to call this macro from any thread.
AVAILABILITY
This macro is available since SDL 3.2.0.
