I've got this Quintus prolog program and this C program and, quite
unreasonably really, I want them to `talk' to each other.

However, the Quintus library predicate popen only allows me to get
hold of one end of the pipe: I can either read from it or write
to it, but not both.

Does anybody either (a) know of an easy way of doing both or (b) have
a library package which exports predicates to do this.

Oh, and on top of that the C program writes its output to standard
error (don't ask). So what I want is to be able to send stuff from
my Quintus program through the pipe to the C program, and pick up 
its output off standard error when its finished munging about with
it.

Don't want much, do I? However, any help with this would be greatly
appreciated. Thanks,

Jeremy
