igc_get_nfc_rule(9)

💅 igc_get_nfc_rule — from the Kernel API Manual, bestie ✨

okay so this is igc_get_nfc_rule(9), a kernel API page, and it's honestly such a clean little function. no cap. let's get into it 🫶

---

✨ NAME ✨

igc_get_nfc_rule — literally just get NFC rule. that's the whole vibe. you want a rule, you get a rule. iconic behavior 💅

---

🎀 SYNOPSIS 🎀

struct igc_nfc_rule * igc_get_nfc_rule (struct igc_adapter *adapter ,
u32 location );

look at that signature. struct igc_nfc_rule * coming back at you, taking an adapter and a location. chef's kiss 🔥

---

🌸 ARGUMENTS 🌸

• adapter — Pointer to adapter. yes queen, the whole adapter. it's giving "pointer to the main character" 👑
• location — Rule location. it's a u32, it tells you where the rule lives. iykyk 🦋

---

⭐ CONTEXT ⭐

Expects adapter->nfc_rule_lock to be held by caller.

⚠️ bestie read this twice — you (the caller) gotta be holding adapter->nfc_rule_lock already. this function is not out here locking things for you, it trusts you completely 🙈

---

💜 RETURN 💜

Pointer to NFC rule at location. If not found, NULL.

so like… you get your rule back, or you get NULL and you gotta handle it. no in-between, no drama 😭
