# SDL_HINT_VIDEO_X11_NET_WM_PING

A variable controlling whether the X11 _NET_WM_PING protocol should be supported.

## Header File

Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_hints.h)

## Syntax

```c
#define SDL_HINT_VIDEO_X11_NET_WM_PING      "SDL_VIDEO_X11_NET_WM_PING"
```

## Remarks

This variable can be set to the following values:

- "0": Disable _NET_WM_PING
- "1": Enable _NET_WM_PING

By default SDL will use _NET_WM_PING, but for applications that know they
will not always be able to respond to ping requests in a timely manner they
can turn it off to avoid the window manager thinking the app is hung. The
hint is checked in CreateWindow.
