NAME
       Signal - send a (POSIX-style) signal to a tool

SYNOPSIS
       Signal(in string theSignal);

DESCRIPTION
       The  Signal  request  asks the handling procid to send itself the indi-
       cated POSIX signal.

       The theSignal argument is the signal to send.

APPLICATION USAGE
       The ttdt_session_join(3), function can be used  to  register  for,  and
       transparently process, the Signal request.

EXAMPLES
       The Signal request can be sent as in the following example:

            Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
                        the_recipient_procid, TTDT_SIGNAL,
                        my_callback);
            tt_message_arg_add(msg, TT_IN, Tttk_string, "SIGHUP");
            tt_message_send(msg);

WARNINGS
       Signal can also be sent as a multicast notice, as an edict to all tools
       in the scope of the message.  The  consequences  of  doing  so  can  be
       severe and unexpected.
