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

SDL_zerop

Clear an object's memory to zero, using a pointer.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

#define SDL_zerop(x) SDL_memset((x), 0, sizeof(*(x)))

Macro Parameters

x	a pointer to the object to clear.

Remarks

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 a pointer to an object, not an object itself, nor an array.

Thread Safety

It is safe to call this macro from any thread.

Version

This macro is available since SDL 3.1.3.
