(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_GetTouchDevices

Get a list of registered touch devices.

Header File

Defined in <SDL3/SDL_touch.h>

Syntax

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 *) Returns a 0 terminated array of touch device IDs or NULL on failure; call SDL_GetError() for more information. This should be freed with 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 3.1.3.
