--- Comment #1 from Peter Hutterer <[email protected]> ---
Just a few notes: the TOUCH capability is assigned to any touch device, even
single-touch touchscreens. Whether it's single touch or multi-touch is not
exposed, but we have device->mt.slots_len with the number of slots internally.
There is no capability API outside of that, the closest we have for querying
specific devices is the libinput_device_<type>_has* set of functions to check
for buttons or keys. So libinput_device_touch_get_num_touches() would fit, and
so would libinput_device_touch_has_multitouch() for a basic boolean check.
CC-ing carlos in case he has any thoughts on using it in mutter.
