damon_stop(9)

💅 damon_stop — Kernel API Manual (section 9, bestie)

okay so you're in the damon_stop(9) page, welcome, this is the Kernel API Manual and we're talking about shutting down monitoring for a whole little squad of contexts. honestly iconic behaviour. let's get into it 🎀

---

✨ NAME ✨

damon_stop — stops the monitorings for a given group of contexts. that's it, that's the whole vibe. it stops them. all of them in the group. periodt 💅

---

🌸 SYNOPSIS 🌸

void damon_stop (struct damon_ctx **ctxs , int nr_ctxs );

literally just hand it your array of context pointers and how many there are, and it goes to work 🫶 no return value, so nothing to check, she just does the thing.

---

🦋 ARGUMENTS 🦋

• ctxs — an array of the pointers for contexts to stop monitoring. yes, pointers, plural, it's a struct damon_ctx ** so it's a pointer-to-pointer situation, we love a double pointer moment ✨ this is the group of contexts getting their monitoring stopped.
• nr_ctxs — size of ctxs. it's an int, and it's how many entries are in that array, so damon_stop knows where to stop looking. no cap, if this number's wrong the vibes are wrong 🙈

bestie pls make sure nr_ctxs actually matches how many context pointers you put in ctxs. that's the size of the array. that's the assignment. 💀
