###### (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_GetTouchDevices Get a list of registered touch devices. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_touch.h) ## Syntax ```c SDL_TouchID* SDL_GetTouchDevices(int *count); ``` ## Function Parameters | | | | ------------- | --------------------------------------------------------------------- | | **count** | a pointer filled in with the number of devices returned, can be NULL. | ## Return Value Returns a 0 terminated array of touch device IDs which should be freed with [SDL_free](SDL_free)(), or NULL on error; call [SDL_GetError](SDL_GetError)() for more details. ## 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 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryTouch](CategoryTouch)
