xcb_configure_window - Configures window attributes

#include <xcb/xproto.h>

xcb_void_cookie_t xcb_configure_window(xcb_connection_t *conn, xcb_window_t window, uint16_t value_mask, const void *value_list);

The XCB connection to X11.
The window to configure.
Bitmask of attributes to change.
New values, corresponding to the attributes in value_mask. The order has to correspond to the order of possible value_mask bits. See the example.

Configures a window's size, position, border width and stacking order.

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_configure_window_checked. See xcb-requests(3) for details.

You specified a Sibling without also specifying StackMode or the window is not actually a Sibling.
TODO: reasons?
The specified window does not exist. TODO: any other reason?
