Returns an xcb_glx_get_pixel_mapfv_cookie_t. Errors have to be handled when calling the reply function xcb_glx_get_pixel_mapfv_reply.
If you want to handle errors in the event loop instead, use xcb_glx_get_pixel_mapfv_unchecked. See xcb-requests(3) for details.
This request does never generate any errors.
