I want to open a named pipe to a running Daemon server. I don't want to start the server when I open a pipe to it. I just want to be able to write data to it while its running. In other words: 

open(HANDLE, "|running_server");
print HANDLE "DATA\n";
close(HANDLE);

I know one way of writing to the mail server is by using a named pipe: 

open(SENDMAIL, "|/usr/lib/sendmail -oi -t -odq")
               or die "Can't fork for sendmail: !\n";

Question: Does anyone know how I could do this?
Thanks
