const void *value_list);
REQUEST ARGUMENTS

ated by xcb_generate_id.

DESCRIPTION
Creates a graphics context. The graphics context can be used with any
drawable that has the same root and depth as the specified drawable.
RETURN VALUE

use xcb_create_gc_checked. See xcb-requests(3) for details.
ERRORS
