DESCRIPTION

RETURN VALUE

68       Returns an xcb_glx_get_doublev_cookie_t. Errors have to be handled when
69       calling the reply function xcb_glx_get_doublev_reply.
70
71       If you want to handle errors in the event loop instead, use
72       xcb_glx_get_doublev_unchecked. See xcb-requests(3) for details.
