another option is to use a TranslateCoordinates request to translate 0,0 
from your window to the root window. The above section of ICCCM also 
contains some words about it.

Untested pseudo-C:

xcb_translate_coordinates_reply_t *reply = 
xcb_translate_coordinates_reply(c, xcb_translate_coordinates(c, 
your_windows, screen->root, 0, 0), NULL);
if (reply) {
    printf("%d %d\n", reply->dst_x, dst_y);
    free(reply);
}

Cheers,
Uli
