# [DESCRIPTION](#DESCRIPTION)

# [RETURN VALUE](#RETURN_VALUE)

Returns an *xcb\_dri2\_wait\_msc\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_dri2\_wait\_msc\_reply*.

If you want to handle errors in the event loop instead, use *xcb\_dri2\_wait\_msc\_unchecked*. See [**xcb-requests(3)**](/man/os/libxcb/xcb-requests.3) for details.
