DESCRIPTION

RETURN VALUE

70       Returns an xcb_glx_get_mapfv_cookie_t. Errors have to be handled when
71       calling the reply function xcb_glx_get_mapfv_reply.
72
73       If you want to handle errors in the event loop instead, use
74       xcb_glx_get_mapfv_unchecked. See xcb-requests(3) for details.
