it uses floats afaik, or just pretends that xemacsen integers have 32
bits ;)
BTW, my first reply wasn't delivered to xemacs-beta＠
because of invalid from address i used, so i will repost it.
Here is example how you could use it to access desktop information:
(let ((xdpy (XOpenDisplay (getenv "DISPLAY"))))
(unwind-protect
(XGetWindowProperty
xdpy (XDefaultRootWindow xdpy)
(XInternAtom xdpy "_NET_CURRENT_DESKTOP")
nil nil nil XA-cardinal)
(XCloseDisplay xdpy)))
That’s not workable for implementing what Jonathan wants to do, though. This
is from one of my current sessions, started in a screen(1) pseudo-tty, with
a gnuclient X11 window:
(getenv "DISPLAY")
=> nil ;; This means we can’t trust getenv
(selected-device)
=> #<x-device on ":0.0" 0x1400f016>
(XOpenDisplay (device-connection (selected-device)))
=> (error "Network error: connection failed, \"Connection refused\",
\"bonbon\", \"X-bonbon:0\"")
;; That was because the connection wasn’t a TCP connection, it was a local
;; unix connection.
