## DESCRIPTION

## RETURN VALUE

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\_input\_grab\_device\_key\_checked*. See **[xcb-requests(3)](/xcb-requests/3.md)** for details.

## ERRORS
