Hello all,
man 2 select states:
"
timeout is an upper bound on the amount of time elapsed before
select()
returns. It may be zero, causing select() to return immediately. (This
is
useful for polling.) If timeout is NULL (no timeout), select() can
block
indefinitely.
"
This... is... confusing.
aka "what the heck is the difference between timeout zero and timeout NULL!?!?"
"It may be zero" should thus definitely be changed into something like
"the timeout value represented by the timeval struct may be zero"
to make sure that people grok the difference between a NULL _pointer_ and a
zero _representation_ of a struct.
This all considering that this is indeed how select(2) works (haven't
actually verified it myself recently).
Thanks for your much needed docu work,
Andreas Mohr
