X Version 11                                      libxcb 1.17.0                                 xcb_create_gc(3)

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

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

       xcb_drawable_error_t
                 The specified drawable (Window or Pixmap) does not exist.

conn      The XCB connection to X11.

       cid       The ID with which you will refer to the graphics context, created by xcb_generate_id.

       drawable  Drawable to get the root/depth from.

       value_mask
                 TODO: NOT YET DOCUMENTED.

       value_list
                 TODO: NOT YET DOCUMENTED.

       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

       If you want to handle errors directly with xcb_request_check instead, use xcb_create_gc_checked. See xcb-requests(3) for details.
