Yes Rick, I'm asking this "indefinitely" issue. Is there anything
that handle this NULL situation a signal, or etc.? How does Linux or
FreeBSD behave?

How select(2) will behave if I give the "utimeout" parameter as
NULL?
According to the man page:
If timeout is not a null pointer, it specifies the maximum interval to
wait for the selection to complete. System activity can lengthen the
interval by an indeterminate amount.
If timeout is a null pointer, the select blocks indefinitely.
To effect a poll, the timeout argument should not be a null pointer, but
it should point to a zero-valued timeval structure.

Nevermind -- yes, block indefinitely, which implies that the program
won't proceed until it receives an umasked signal and exits or a file
descriptor becomes available in the 'infinite' time frame.
That would essentially be the same as listen or send though with
blocking sockets, correct?
