FUNCTION::SID(3stap)

✨ NAME ✨

function::sid — bestie, this one hands you the session ID of the process you're currently vibing in 💅

(also hi, this is a page from FUNCTION::SID(3stap), the Context Functions corner of the manual 🎀)

---

🌸 SYNOPSIS 🌸

sid:long()

That's it. That's the whole thing. No args, no drama, just a return value 🫶

---

🎀 ARGUMENTS 🎀

• None — literally nothing. Empty hands. She takes no arguments and she doesn't want any 🙈

---

💖 DESCRIPTION 💖

okay so, quick lore drop 📖 — the session ID of a process is the process group ID of the session leader. That's the whole definition, no cap.

And where does this live? The session ID is stored in the signal_struct since Kernel 2.6.0 ⭐. So if you're on anything older than that, this is not the vibe. But if you're on 2.6.0 or later, she's right there waiting for you, iconic behavior honestly 👑
