SIGNAL(4)

✨ NAME ✨

Okay bestie, welcome to the Signal page — special file manual, aka the SIGNAL(4) tea you asked for 💅✨

Signal — send a (POSIX-style) signal to a tool.

🌸 SYNOPSIS 🌸

Signal(in string theSignal);

🦋 DESCRIPTION 🦋

So basically, the Signal request asks the handling procid to send itself the indicated POSIX signal. The theSignal argument is literally the signal you're sending — that's the whole vibe 💖

🎀 APPLICATION USAGE 🎀

You can use ttdt_session_join(3) to register for the Signal request and have it transparently processed. Iconic, lowkey ✨

🍓 EXAMPLES 🍓

You can send the Signal request like this, bestie:

       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 💀

Heads up! 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. Not a cute little oopsie — fr fr, be careful 😭

💖 That's the whole page! The footer only says Signal(special file) — no separate source, version, or date text is printed here, so we're not inventing any. Byeee, bestie 🫶🎀
