###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!)
# SDL_GetWindowID

Get the numeric ID of a window.

## Header File

Defined in [SDL_video.h](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_video.h), but apps should use `#include <SDL3/SDL.h>`

## Syntax

```c
SDL_WindowID SDL_GetWindowID(SDL_Window *window);

```

## Function Parameters

|                |                     |
| -------------- | ------------------- |
| **window**     | the window to query |

## Return Value

Returns the ID of the window on success or 0 on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

The numeric ID is what [SDL_WindowEvent](SDL_WindowEvent) references, and
is necessary to map these events to specific [SDL_Window](SDL_Window)
objects.

## Version

This function is available since SDL 3.0.0.
