FUNCTION::RAISE(3stap)

💖 FUNCTION::RAISE 💖

okay so bestie, we're in the Guru tapsets corner of the SystemTap Tapset Reference (that's the 3stap girlies, iykyk) and today's main character is a little function called raise. yes she's tiny. yes she's powerful. let's get into it 🫶

---

✨ NAME ✨

function::raise — raise a signal in the current thread 💅

like. literally just that. she raises a signal. in the current thread. no cap.

---

✨ SYNOPSIS ✨

raise(signo:long)

that's it, that's the whole vibe 🌸

---

✨ ARGUMENTS ✨

• signo — the signal number 🔥 just a lil number, the signal you wanna send, that's her

---

✨ DESCRIPTION ✨

okay so here's the tea 🍓 this function calls the kernel send_sig routine on the current thread, and it hands over the given raw unchecked signal number. raw. unchecked. she does not do a vibe check on that number first, she just sends it — so pls know what you're doing 💀

and lowkey important: she may raise an error if send_sig failed. not "will", may. so keep an eye out 👀

also — and this is the big one — it requires guru mode. guru mode is not a casual lil thing, bestie, it's the "I know exactly what I'm doing" mode 👑 so don't just wander in there.

⚠️ guru mode required. signo is raw and unchecked. send_sig can fail and this can throw an error. be mindful, queen 🎀
