SDL_GetTouchDevices - Man Page

Defined in SDL3/SDL_touch.h

#include "SDL3/SDL.h"

SDL_TouchID * SDL_GetTouchDevices(int *count);

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.

count

a pointer filled in with the number of devices returned, may be NULL.

( 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.

This function is available since SDL 3.2.0.
