PROBE::SIGNAL.FLUS(3stap)

✨ NAME ✨

okay so bestie, welcome to PROBE::SIGNAL.FLUS — that's a page from the Signal Tapset of the SystemTap Tapset Reference, and it's all about one lil probe:

probe::signal.flush — flushing all pending signals for a task 💅

---

🎀 SYNOPSIS 🎀

probe signal.flush {}

that's it. that's the whole vibe. no args, no drama, just a probe point sitting there ready to catch the moment a task gets its pending signals yeeted into the void 🌸

---

🌈 VALUES 🌈

these are the goodies you can read inside the probe handler — the little data drops that show up when the probe fires 🫶

• name — the name of the probe point. yes bestie, the probe knows its own name, main character energy honestly 👑
• task — the task handler of the process that's doing the flushing. so like, who is out here clearing signals.
• pid_name — the name of the process associated with the task performing the flush. the friendly lil label, not the number 💖
• sig_pid — the PID of the process associated with the task performing the flush. now this is the actual number, the numeric ID, no nickname, fr fr 🔥

not me emphasising this: pid_name and sig_pid are two different things!! one is the name, one is the PID. do not mix them up or you will be confused and I will cry 😭
