# [REQUEST ARGUMENTS](#REQUEST_ARGUMENTS)

[*conn*](#conn)

The XCB connection to X11.

[*screen*](#screen)

TODO: NOT YET DOCUMENTED.

# [REPLY FIELDS](#REPLY_FIELDS)

[*response\_type*](#response_type)

The type of this reply, in this case *XCB\_XF86DRI\_OPEN\_CONNECTION*. 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.

[*length*](#length)

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

[*sarea\_handle\_low*](#sarea_handle_low)

TODO: NOT YET DOCUMENTED.

[*sarea\_handle\_high*](#sarea_handle_high)

TODO: NOT YET DOCUMENTED.

[*bus\_id\_len*](#bus_id_len)

TODO: NOT YET DOCUMENTED.

# [DESCRIPTION](#DESCRIPTION)

# [RETURN VALUE](#RETURN_VALUE)

Returns an *xcb\_xf86dri\_open\_connection\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_xf86dri\_open\_connection\_reply*.

If you want to handle errors in the event loop instead, use *xcb\_xf86dri\_open\_connection\_unchecked*. See [**xcb-requests(3)**](/man/os/libxcb/xcb-requests.3) for details.

# [ERRORS](#ERRORS)
