## DESCRIPTION

## 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)](/xcb-requests/3.md)** for details.

## ERRORS

This request does never generate any errors.
