# SDL_zeroa Clear an array's memory to zero. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c #define SDL_zeroa(x) SDL_memset((x), 0, sizeof((x))) ``` ## Macro Parameters | | | | ----- | ------------------ | | **x** | an array to clear. | ## Remarks This is wrapper over [SDL_memset](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. ## Version This macro is available since SDL 3.2.0. ## See Also - [SDL_zero](SDL_zero) - [SDL_zeroa](SDL_zeroa) ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryStdinc](CategoryStdinc)
