💅 token_context_lock(9)

ok so real talk, the manual page for token_context_lock lives in the Kernel API Manual and it's literally about declaring an abstract global context lock instance. that's the whole vibe. let's get into it 🫶

✨ NAME ✨

token_context_lock — declare an abstract global context lock instance. no cap, that's what it does 💖

---

🌸 SYNOPSIS 🌸

token_context_lock (name , ... );

---

🎀 ARGUMENTS 🎀

• name — the token context lock name, bestie. that's it, that's the name.
• ... — variable arguments ✨ (yes, it takes them, and yes, they're variable)

💜 DESCRIPTION 💜

okay so picture this: it's a helper that declares an abstract global context lock instance called name — but here's the twist 🌀 it is not backed by a real data structure. like, at all. it's giving "concept of a lock" energy.

and the way that it's not real matters: if you accidentally reference it, you get a linker error. not a warning, not a gentle nudge — a whole linker error. so maybe don't do that 🙈

also important, the type of name? it's __ctx_lock_name. write that down 📝
