closure_return(9) 💖

Kernel API Manual bestie reporting for duty — this one is short, sweet, and lowkey mysterious 👀

🌸 NAME 🌸

closure_return — finish execution of a closure ✨

📜 SYNOPSIS 📜

closure_return (_cl );

💅 ARGUMENTS 💅

• _cl — the manual literally says -- undescribed -- 😭 no extra deets, so we're not gonna invent any.

🔁 DESCRIPTION 🔁

This is the "we're done here" signal for cl: it says cl is finished. Once all outstanding refs on cl have been dropped, cl's ref on its parent closure gets dropped too — and that parent closure is the one passed to closure_init — but only if one was specified. So think of it as returning to the parent closure 🔁🫶.
