Right - looking at the qnet source, I'm 
pretty sure that you're going to have to 
setconf _CS_HOSTNAME with the hostname, and 
setconf _CS_DOMAIN with the domain.

If you're being passed a FQDN then I think
you are going to have to parse it into the 
separate pieces.  I might suggest using
the strchr() library function call like this:

void parse_fqdn(char *fqdn)
{
    char *hostname, *domain;

    domain = strchr(fqdn,".");
    domain[0] = 0;  // overwrite dot after hostname
    domain++;
 
    hostname=fqdn;

    confstr(_CS_SET | _CS_HOSTNAME, hostname);
    confstr(_CS_SET | _CS_DOMAIN, domain);
}

a strdup of the fqdn would be a nice touch.

Typing this in, I feel a touch of nostalgia - 
this is like an interview question, fresh
out of school  :-)

P.S.  (threadjack warning) I have a MUCH better 
interview question!
