uint32_t value_mask, const void *value_list);
REQUEST ARGUMENTS

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.

The X server could not allocate the requested resources (no
memory?).
