- It was a point of contention for a long time, for starters just to see
- what dot-group would handle it. Last I heard, it was pushed off into
- a future .1 addendum.
-
- I personally find "poll" (SV's view of the problem) nicer than select
- - at least from a user's point of view. And the man pages for select
- are so vaguely worded that there is no one way to do it. It may seem
- like an intuitive function, but there are many dark corners in select
- which different vendors have implemented in different ways.
-
- Of course, the irony of this is that SVR4 supports select as well as
- poll, so it is tempting to consider select the more portable of the
- two despite its problems.
