    NAME
	init_inet_daemon - obtain socket accepted by the inetd

    SYNOPSIS
	int init_inet_daemon(void);

    FUNCTION
	Obtain the server socket accepted by the inetd, the Internet
	super-server.

    RETURN VALUES
	socket descriptor if successful, -1 with specific error code
	on errno otherwise.

    ERRORS
	ENXIO	  - The process was not started by the inetd.

    NOTES
	If the process was started by the inetd, but the ObtainSocket()
	call fails, then this function exit()s with some specific exit
	code, so that inetd can clean up the unobtained socket.

	Use the net.lib function set_socket_stdio() to redirect stdio,
	stdout and stderr to the returned socket, if necessary.

    SEE ALSO
	serveraccept(), set_socket_stdio(), bsdsocket/ObtainSocket(),
	netutil/inetd
