RE: Help with this code snippet please (Tom Wood)

Thank you, I think the major problem with my code is that I'm not following
the event-driven model to the T. I found an example from an earlier post after I posted this message that clued me
in on how tux modules work! I'm off and running now! Thanks again!

this should be

if(tux(TUX_ACTION_GET_OBJECT, req) < 0 || req->error)

> 	strcpy(req->objectname, "REVIEW.GIF");

You're missing some vital steps; after GET_OBJECT you must call
TUX_ACTION_SEND_OBJECT and TUX_ACTION_FINISH_CLOSE_REQ, preferably in the
event-driven model (which you haven't used properly here).

Again, demo2.c shows how to do this correctly.
