+ * @defgroup xcb__cursor_context_t XCB Cursor Functions
+ *
+ * These functions are the equivalent of libXcursor, but re-implemented for
+ * XCB. They respect the user’s configured cursor theme when loading cursors,
+ * specified by the X resources setting "Xcursor.theme".
+ *
+ * Here is how you would use these functions to change the X11 root window
+ * cursor to "watch":
+ * @code
+ * int screennr;
+ * xcb_connection_t *conn = xcb_connect(NULL, &screennr);
+ * if (conn == NULL || xcb_connection_has_error(conn))
+ *     err(EXIT_FAILURE, "Could not connect to X11");
+ *
+ * xcb_screen_t *screen = xcb_aux_get_screen(conn, screennr);
+ * xcb_cursor_context_t *ctx;
+ * if (xcb_cursor_context_new(conn, screen, &ctx) < 0)
+ *     err(EXIT_FAILURE, "Could not initialize xcb-cursor");
+ *
+ * xcb_cursor_t cid = xcb_cursor_load_cursor(ctx, "watch");
+ *
+ * xcb_screen_t *screen = xcb_setup_roots_iterator(xcb_get_setup(conn)).data;
+ * xcb_change_window_attributes(conn, screen->root, XCB_CW_CURSOR, (uint32_t[]){ cid });
+ * xcb_free_cursor(conn, cid);
+ * xcb_flush(conn);
+ *
+ * xcb_cursor_context_free(ctx);
+ * xcb_disconnect(conn);
+ * @endcode
+ *
