Number 20 of 20: event ports
By ahl on Jul 21, 2004
Bart Smaalders has written some great stuff about event ports including an extensive coding example. Event ports provide a single API for tying together disparate souces of events. We had baby steps in the past with poll(2) and select(3c), but event ports let you have the file descriptor and timer monitoring as well as dealing with asynchronous I/O and your own custom events.
