# [DESCRIPTION](#DESCRIPTION)

# [RETURN VALUE](#RETURN_VALUE)

Returns an *xcb\_xkb\_get\_device\_info\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_xkb\_get\_device\_info\_reply*.

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

# [ERRORS](#ERRORS)

This request does never generate any errors.
