## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *output*

  TODO: NOT YET DOCUMENTED.

- *config\_timestamp*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

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

- *sequence*

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

- *length*

  The length of the reply, in words (a word is 4 bytes).

- *status*

  TODO: NOT YET DOCUMENTED.

- *timestamp*

  TODO: NOT YET DOCUMENTED.

- *crtc*

  TODO: NOT YET DOCUMENTED.

- *mm\_width*

  TODO: NOT YET DOCUMENTED.

- *mm\_height*

  TODO: NOT YET DOCUMENTED.

- *connection*

  TODO: NOT YET DOCUMENTED.

- *subpixel\_order*

  TODO: NOT YET DOCUMENTED.

- *num\_crtcs*

  TODO: NOT YET DOCUMENTED.

- *num\_modes*

  TODO: NOT YET DOCUMENTED.

- *num\_preferred*

  TODO: NOT YET DOCUMENTED.

- *num\_clones*

  TODO: NOT YET DOCUMENTED.

- *name\_len*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

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

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

## ERRORS

This request does never generate any errors.
