Signal(4) DEVICES AND NETWORK INTERFACES Signal(4)
Signal request - send a (POSIX-style) signal to a tool
Signal(in string theSignal);
The Signal request asks the handling procid to send itself
the indicated POSIX signal.
The theSignal argument is the signal to send.
The ttdt_session_join(3), function can be used to register
for, and transparently process, the Signal request.
The Signal request can be sent as in the following example:
Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
tt_message_arg_add(msg, TT_IN, Tttk_string, "SIGHUP");
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.
