The type of this reply, in this case XCB_GLX_GET_MAPFV. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
The sequence number of the last request processed by the X11 server.
The length of the reply, in words (a word is 4 bytes).
TODO: NOT YET DOCUMENTED.
TODO: NOT YET DOCUMENTED.

Returns an xcb_glx_get_mapfv_cookie_t. Errors have to be handled when calling the reply function xcb_glx_get_mapfv_reply.

If you want to handle errors in the event loop instead, use xcb_glx_get_mapfv_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.
