next in thread | raw e-mail | index | archive | help
FreeBSD man page for signal(3) states that
Unlike previous signal facilities, the handler func() remains
installed after a signal has been delivered.
What "previous" signal facilities is this referring to? I've seen a
lot of code where a signal handler function would re-install itself
the first thing. But I've tested, and that doesn't appear to be
necessary at least on FreeBSD and Linux. Is that for portability, or
is that something else?
Many thanks,
