💅 rt2x00queue_for_each_entry — Kernel API Manual, bestie edition 🎀

okay so you found a page from the Kernel API Manual and it's about rt2x00queue_for_each_entry(9) — yes it's a whole mouthful, no I will not be shortening it, and yes we're gonna get through it together. grab a snack 🍓

---

✨ NAME ✨

rt2x00queue_for_each_entry — literally just loop through all entries in the queue. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

bool rt2x00queue_for_each_entry (struct data_queue *queue , enum
queue_index start , enum queue_index end , void *data , bool
(*fn)(struct queue_entry *entry, void *data) );

look at her go. returns a bool, takes five things, one of which is a function pointer because of course it is 😭

---

💖 ARGUMENTS 💖

• queue — Pointer to data_queue. our main character, the queue itself 👑
• start — enum queue_index Pointer to start index. where the little walk begins 🌈
• end — enum queue_index Pointer to end index. where the walk stops, bestie 💅
• data — Data to pass to the callback function. lil care package for your callback 🎁
• fn — The function to call for each struct queue_entry. this is the callback, the one doing the actual work per entry, no cap ✨

---

🦋 DESCRIPTION 🦋

so here's the tea: this walks through all entries in the queue, in chronological order. periodt.

which means — and i need you to hear this — it starts at the current start pointer and keeps walking through the queue until it reaches the end pointer. that's it. that's the whole journey. 🚶‍♀️

and here's the iconic part: if fn returns true for an entry, rt2x00queue_for_each_entry will stop processing and return true as well. so like, your callback can call it off early. main character behaviour honestly 🔥

ngl the SEE ALSO section is giving family reunion energy 🙈 but that's how you know this function has people. iykyk.

and that's the page bestie!! 🫶 this little cutie comes to you from ./drivers/net/wireless/ralink/... and she's stamped October 2026 — so go forth, loop through those entries chronologically, and remember: the callback can always make it stop 💀✨ rt2x00queue_for_each_entry(9), you ate 💅👑
