* Start the Telnet daemon.

* Parameters:
* config A pointer to a configuration structure that characterizes the

* on the caller's stack because it is not retained by the
* daemon.
*
* Return:
* The process ID (pid) of the new Telnet daemon is returned on
* success; A negated errno is returned if the daemon was not successfully
* started.
