you will get a response within a pre-defined time frame.
There are some Unix systems (e.g.: MERT (?), and QNX)
which ARE "real-time", but most other Unix systems are
configured/designed to be more equitable multi-user systems
where every user usually gets a relatively fair share of
the computer resources and in that form it is virtually
impossible to guarantee any particular short time frame
(i.e.: millisecond, or microsecond) response.
I hope that helps (without going in to any real detail).Quote:>I'd appreciate your replies.
