# SDL_zero

Clear an object's memory to zero.

## Header File

Defined in [<SDL3/SDL_stdinc.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h)

## Syntax

```c
#define SDL_zero(x) SDL_memset(&(x), 0, sizeof((x)))
```

## Macro Parameters

|       |                      |
| ----- | -------------------- |
| **x** | the object to clear. |

## Remarks

This is wrapper over [SDL_memset](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.

## Thread Safety

It is safe to call this macro from any thread.

## Version

This macro is available since SDL 3.2.0.
