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 indicated 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.
