A collegue at work is going to be doing some programming (in C) to
handle incoming data.  I would appreciate some references I could pass
on to him.  He's going to have a regular program doing other things
but when some new data comes in he wants to process it. 

I had done some of this in a microprocessor interfacing class in
college - every time data from an A/D came in, an interrupt was
triggered which went off and did its thing - so I think this is how it
would be handled.
