c - How to register events using libxcb-xinput -

i'm trying listen touch events (touch_begin, touch_update, touch_end , touch_ownership) on root window.
touch events aren't directly integrated xcb, have use input extension (libxcb-xinput).

i managed set event listener events coming input extension, can't figure out how register events want listen to.

i tried using xcb_input_xi_select_events(), function takes parameter of type xcb_input_event_mask_t, while enum containing event masks of type xcb_input_xi_event_mask_t , there no obvious way cast them.

for reason think xcb_input_xi_select_events() wrong function, have no idea function use instead.

my non working code looks that:

xcb_input_event_mask_t mask[] = {     xcb_input_xi_event_mask_touch_begin     | xcb_input_xi_event_mask_touch_end     | xcb_input_xi_event_mask_touch_update     | xcb_input_xi_event_mask_touch_ownership }; xcb_input_xi_select_events(dpy, root, 4, mask); 

the core throws "large integer implicitly truncated unsigned type" warning @ compile time , "failed request: (null), (null): 0x000000d5" error @ runtime.

(i'm pretty new c , xcb, please forgive obvious errors)

i found solution this.

const uint32_t mask[] = {     xcb_input_xi_event_mask_touch_begin     | xcb_input_xi_event_mask_touch_update     | xcb_input_xi_event_mask_touch_end     | xcb_input_xi_event_mask_touch_ownership }; const uint32_t modifiers[] = {xcb_input_modifier_mask_any};  xcb_input_xi_passive_grab_device(     dpy,      xcb_current_time,      root,     xcb_cursor_none,     0, // detail - used xipassivegrab     xcb_input_device_all_master,     1, // num_modifiers     1, // mask_len     xcb_input_grab_type_touch_begin,     xcb_input_grab_mode_22_touch,     xcb_input_grab_mode_22_async,     xcb_input_grab_owner_no_owner,     mask,     modifiers ); 

it looks bit cryptic, works.
