You can use the NSFileHandle if you want to maintain some sort of 
MacOS-X compatibility (though the MacOS-X compatible part of the api 
won't let you get write events), or you can use the 
NSRunLoop(GNUstepExtensions) category methods to watch a descriptor ... 
in which case an object of your choice receives a callback when an 
event occurs (see the RunLoopEvents protocol).
