## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *crtc*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_RANDR\_GET\_CRTC\_TRANSFORM*. 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).

- *pending\_transform*

  TODO: NOT YET DOCUMENTED.

- *has\_transforms*

  TODO: NOT YET DOCUMENTED.

- *current\_transform*

  TODO: NOT YET DOCUMENTED.

- *pending\_len*

  TODO: NOT YET DOCUMENTED.

- *pending\_nparams*

  TODO: NOT YET DOCUMENTED.

- *current\_len*

  TODO: NOT YET DOCUMENTED.

- *current\_nparams*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

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

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

## ERRORS

This request does never generate any errors.
