// a connection endpoint (socket or TLI).  If so, that endpoint has been
// set up as an RPC connection by inetd and we should use it instead of
// creating our own.  If fd 0 is NOT a endpoint, we assume we\'re started
// from the shell, and create a new endpoint and redirect the portmapper to it.

// This is complicated by the fact that the inetd.conf file in Solaris 2.3
// and Solaris 2.3. specifies that rpc.ttdbserverd is rpc/tcp, not rpc/tli.
// We want this version of rpc.ttdbserverd to run on Solaris 2.3, so we have
// to cater to it by checking for a tcp socket being passed in; if there is
