nfc_targets_found(9)

✨ nfc_targets_found(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's short but she's important, so let's get into it 🫶

---

🌸 NAME 🌸

nfc_targets_found — the lil function that says "bestie, we found targets" ✨

---

🦋 SYNOPSIS 🦋

int nfc_targets_found (struct nfc_dev *dev , struct nfc_target *targets
, int n_targets );

---

🎀 ARGUMENTS 🎀

• dev — the nfc device that found the targets, like the main character who spotted them 👑
• targets — array of nfc targets found, literally the whole friend group 🫶
• n_targets — targets array size, aka how many besties are in the group chat 💖

---

⭐ DESCRIPTION ⭐

so here's the vibe: the device driver must call this function when one or many nfc targets are found. no cap, it's required 🙈

and after calling this function? the device driver must stop polling for targets. like, wrap it up, the search is over periodt 💅

---

💀 NOTE 💀

listen up, this part matters fr fr 🔥

This function can be called with targets=NULL and n_targets=0 to notify a driver error — meaning that the polling operation cannot complete. so yeah, NULL isn't always a bug, sometimes it's just the sad truth 😭

IMPORTANT: this function must not be called from an atomic context. that's a hard no, not a vibe check you can pass 🚫

In addition, it must also not be called from a context that would prevent the NFC Core to call other nfc ops entry point concurrently. like, don't be that person blocking the whole group chat from typing, okay? 💀
