DESCRIPTION

31       Creates a graphics context. The graphics context can be used with any
32       drawable that has the same root and depth as the specified drawable.
33

RETURN VALUE

35       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the
36       event loop.
37
38       If you want to handle errors directly with xcb_request_check instead,
39       use xcb_create_gc_checked. See xcb-requests(3) for details.
