###### (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_HINT_GAMECONTROLLER_IGNORE_DEVICES_EXCEPT

If set, all devices will be skipped when scanning for game controllers except for the ones listed in this variable.

## Header File

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

## Syntax

```c
#define SDL_HINT_GAMECONTROLLER_IGNORE_DEVICES_EXCEPT "SDL_GAMECONTROLLER_IGNORE_DEVICES_EXCEPT"
```

## Remarks

The format of the string is a comma separated list of USB VID/PID pairs in
hexadecimal form, e.g.

0xAAAA/0xBBBB,0xCCCC/0xDDDD

The variable can also take the form of "@file", in which case the named
file will be loaded and interpreted as the value of the variable.

This hint can be set anytime.

## Version

This hint is available since SDL 3.0.0.
