# SDL_GetTouchDevices

Get a list of registered touch devices.

## Header File

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

## Syntax

```c
SDL_TouchID * SDL_GetTouchDevices(int *count);
```

## Function Parameters

|       |           |                                                                       |
| ----- | --------- | --------------------------------------------------------------------- |
| int * | **count** | a pointer filled in with the number of devices returned, may be NULL. |

## Return Value

([SDL_TouchID](SDL_TouchID) *) Returns a 0 terminated array of touch device
IDs or NULL on failure; call [SDL_GetError](SDL_GetError)() for more
information. This should be freed with [SDL_free](SDL_free)() when it is no
longer needed.

## Remarks

On some platforms SDL first sees the touch device if it was actually used.
Therefore the returned list might be empty, although devices are available.
After using all devices at least once the number will be correct.

## Version

This function is available since SDL 3.2.0.
