Finding out socket/pipe connectivity status

Hi,


when a pipe/socket is broken, the process trying to read/write to it
gets SIGPIPE. Is there a way to detect whether the next read/write will
trigger a SIGPIPE? select() does not seem helpful here.

My specific case is "ssh server svprogram", in which the ssh process is
locally terminated with ^C, and the svprogram continues to run on the
server (good so), and when a socket breaks, it should cleanly shut down -
ideally before the next read/write is attempted.


thanks,
Jan
