# [REPLY FIELDS](#REPLY_FIELDS)

[*response\_type*](#response_type)

The type of this reply, in this case *XCB\_RANDR\_GET\_SCREEN\_INFO*. This field is also present in the *xcb\_generic\_reply\_t* and can be used to tell replies apart from each other.

[*sequence*](#sequence)

The sequence number of the last request processed by the X11 server.

# [DESCRIPTION](#DESCRIPTION)

# [RETURN VALUE](#RETURN_VALUE)

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

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

# [ERRORS](#ERRORS)
