REPLY FIELDS
response_type
The type of this reply, in this case XCB_GLX_GET_DOUBLEV.
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).
Returns an xcb_glx_get_doublev_cookie_t. Errors have to be handled when
calling the reply function xcb_glx_get_doublev_reply.
If you want to handle errors in the event loop instead, use
xcb_glx_get_doublev_unchecked. See xcb-requests(3) for details.
ERRORS
This request does never generate any errors.
