ogle_stdin and question on exiting

I put together an ugly, text-based front end to ogle for use as a
connection between ogle and a custom remote-control setup.  Perhaps
this will be useful to someone.

This was based on ogle_ir by Rossen Tchobanski.

While writing ogle_stdin, I had the problem that I wanted to be able
to make Ogle exit, but there doesn't seem to be a way to do that
through the control API.  DVDCloseNav() closes the connection, but the
player keeps on running.  I solved my dilemma by calling
system("killall ogle_nav"), but that's hardly satisfying.  Is there
some mechanism for telling ogle to clean-up and quit that I didn't
see?
