__xa_set_mark(9)

🦋 NAME 🦋

__xa_set_mark — bestie, this is the one that sets this mark on this entry while you're already holding the lock 💅 no cap.

---

✨ SYNOPSIS ✨

void __xa_set_mark (struct xarray *xa , unsigned long index , xa_mark_t mark );

---

🎀 ARGUMENTS 🎀

• xa — the XArray itself. the main character structure fr 🫶
• index — index of the entry you're eyeing up. that's the slot, not the thing in it 👑
• mark — mark number. which little tag you're slapping on 🏷️

---

💖 DESCRIPTION 💖

so here's the vibe check 🌸 you go to set a mark on an entry — but if that entry is NULL? it does not succeed. attempting to set a mark on a NULL entry does not succeed, periodt. lowkey that's the whole personality of this function 💀

---

🔥 CONTEXT 🔥

any context, king — any context at all ✨ but (and this is the important bit, ngl) it expects xa_lock to be held on entry. so like… you already locked it. this function is not doing that for you, bestie 🙈

⚠️ xa_lock must be held on entry — that's not a suggestion, that's the assignment 💅
