### Reply function

### Reply accessors

uint32\_t \***xcb\_input\_xi\_query\_pointer\_buttons**(const xcb\_input\_xi\_query\_pointer\_request\_t \**reply*);

int **xcb\_input\_xi\_query\_pointer\_buttons\_length**(const xcb\_input\_xi\_query\_pointer\_reply\_t \**reply*);

xcb\_generic\_iterator\_t **xcb\_input\_xi\_query\_pointer\_buttons\_end**(const xcb\_input\_xi\_query\_pointer\_reply\_t \**reply*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *window*

  TODO: NOT YET DOCUMENTED.

- *deviceid*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_INPUT\_XI\_QUERY\_POINTER*. 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).

- *root*

  TODO: NOT YET DOCUMENTED.

- *child*

  TODO: NOT YET DOCUMENTED.

- *root\_x*

  TODO: NOT YET DOCUMENTED.

- *root\_y*

  TODO: NOT YET DOCUMENTED.

- *win\_x*

  TODO: NOT YET DOCUMENTED.

- *win\_y*

  TODO: NOT YET DOCUMENTED.

- *same\_screen*

  TODO: NOT YET DOCUMENTED.

- *buttons\_len*

  TODO: NOT YET DOCUMENTED.

- *mods*

  TODO: NOT YET DOCUMENTED.

- *group*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_input\_xi\_query\_pointer\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_input\_xi\_query\_pointer\_reply*.

If you want to handle errors in the event loop instead, use *xcb\_input\_xi\_query\_pointer\_unchecked*. See **[xcb-requests(3)](/xcb-requests/3.md)** for details.

## ERRORS

This request does never generate any errors.
