[net.unix] Interrupting a read

byrne%TARTAN@CMU-CS-C.ARPA (01/04/84)

From:  Steve <byrne%TARTAN@CMU-CS-C.ARPA>

OS: 4.2BSD
Problem:
	I want to read from a terminal a certain number of
	characters within a given time.  If the read doesn't get
	the proper number of characters within the given time
	limit, I want the read to terminate, and possibly signal
	some sort of error (just returning -1 as its value would be
	find).  

	This worked in 4.1, but I can't figure out a way to make
	it work under 4.2.  Any clues?
