To register in a session other than the initial session, your
program must find the name of the other session, set the new session
as the default, and register with the ToolTalk service.
The following code sample shows how to join an X session named
somehost:0 that is not your initial session.
char *my_session;
char *my_procid;
my_session = tt_X_session("somehost:0");
tt_default_session_set(my_session);
my_procid = tt_open();
ttfd = tt_fd();

tt_X_session();
This call retrieves the name of the session associated with
an X display server. tt_X_session() takes the argument char *xdisplay_name
where xdisplay_name is the name of an X display server (in this
example, somehost:0, :0).
tt_default_session_set();
This call sets the new session as the default session.
tt_open();
This call returns the procid for your process and sets it
as the default procid.
tt_fd();
This call returns a file descriptor for your current procid.
