[Xcb] Examples on using xcb-util-wm?

[Christophe Lohr]

Hi,
  May I ask another question: what is the purpose of 
xcb_ewmh_get_*_from_reply() functions?

Let's say I want to check if a given windows is fullscreen.
The answer is within atoms returned by xcb_ewmh_get_wm_state_reply().
Does xcb_ewmh_get_wm_state_from_reply() helps me to check
_NET_WM_STATE_FULLSCREEN?
How?

Best regards
Christophe
