select() as a user-level call will never go away; there is a large base of code that uses it. poll() is faster (it doesn't have to do bit twiddling), and it's interface is cleaner (it can report invalid fd's, something select() can't do). As its functionality is a superset of select()'s, it is used as the internal implementation for select(). As for new code, use whichever you are comfortable with. Personally, I would recommend poll(), since it provides some added functionality over select() that makes for easier programming. -- Jonathan To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
