SYNOPSIS

Request function
xcb_void_cookie_t
xcb_create_gc(xcb_connection_t *conn,
xcb_gcontext_t cid, xcb_drawable_t drawable,
uint32_t value_mask, const void *value_list);
REQUEST ARGUMENTS
- 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

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
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.
ERRORS
- 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.
- xcb_font_error_t
- TODO: reasons?
- xcb_match_error_t
- TODO: reasons?
- xcb_pixmap_error_t
- TODO: reasons?
- xcb_value_error_t
