syslog.h has declarations for the system logging functions - syslog(), etc.
This is used on Unix systems to write messages to the log file(s) via a
logging daemon. There are "facilities" (kernel, mail, etc.) and priorites,
which can be used to control where the messages go, so that you can separate
kernel messages from mail messages.

It's part of the Single Unix Specification.

I wrote a basic syslog implementation using Windows mailslots once. It's in my
libmslot library - see:

    http://www.phekda.freeserve.co.uk/richdawe/mysoft.html#libmslot

It needs a logging daemon to do anything useful. The other thing to bear in
mind is that Windows mailslots are not a reliable communication mechanism -
messages may get dropped, when the queues fill up. Whether that's acceptable
enough depends on what you're logging.
