NAME
SDL_zero - Clear an object's memory to zero.
SYNOPSIS
#include <SDL3/SDL_stdinc.h>
#define SDL_zero(x) SDL_memset(&(x), 0, sizeof((x)))
DESCRIPTION
This is wrapper over SDL_memset that handles calculating the object size, so there's no chance of
copy/paste errors, and the code is cleaner.
This requires an object, not a pointer to an object, nor an array.
MACRO PARAMETERS
x the object to clear.
THREAD SAFETY
It is safe to call this macro from any thread.
AVAILABILITY
This macro is available since SDL 3.2.0.
