getting the system's domain name in a C program

[Jim O'Connor]

Is there a system call or library function that is supposed to return the
name of the current host, complete with the domain attached?

I'm a little confused, since when I set up TCP/IP on a Xenix machine, the
installation scripts created the command "hostname tiamat.fsc.com" in the
TCP/IP startup file, so using "hostname" or "gethostname()" returns the
whole thing, and I can always use "uanme" to get just the host name with
out the domain part.

However, when I installed TCP/IP on our HP 9000 Model 815 machine, the
installation created the command "hostname guinan" in the TCP/IP start
up file.  So, on guinan, I don't get the domain name with "gethostname".

Which way is "right"?  Is there a "right" way?

Thanks for any help.
