DRI is a protocol which is here to allow X GL client to directly talk with GL driver and GL driver to talk with X to know where to render. It's not intended to be used by anyone else beyond GL driver or X server. What you want is simply a GL application and there is tons of example out there on how to do one, you could also find examples in mesa/progs/* mese/progs/trivial/tri-* for instance show how to render a simple triangle. So GL app will talk to GL driver which will use DRI on your computer if it's enabled.
