# SDL_HINT_GAMECONTROLLERCONFIG_FILE

A variable that lets you provide a file with extra gamecontroller db entries.

## Header File

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

## Syntax

```c
#define SDL_HINT_GAMECONTROLLERCONFIG_FILE "SDL_GAMECONTROLLERCONFIG_FILE"
```

## Remarks

The file should contain lines of gamecontroller config data, see
