💖 nfc_start_poll(9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual, where today's main character is nfc_start_poll(9) ✨ lowkey iconic of you to be reading kernel docs, fr fr 🫶

---

🌸 NAME 🌸

nfc_start_poll — start polling for nfc targets 💅

---

✨ SYNOPSIS ✨

int nfc_start_poll (struct nfc_dev *dev , u32 im_protocols , u32
tm_protocols );

---

🎀 ARGUMENTS 🎀

• dev — the nfc device that must start polling. yes, that one, she's the one doing the work 🦋
• im_protocols — bitset of nfc initiator protocols to be used for polling ✨ literally a little bitset of vibes (protocol vibes)
• tm_protocols — bitset of nfc transport protocols to be used for polling 🌈 also a bitset, also important, don't skip her

---

💜 DESCRIPTION 💜

so the way this works is: the device just stays polling for targets 😌 like she's posted up in the group chat waiting for someone to reply.

• she keeps polling until a target is found 🎯
• OR until the nfc_stop_poll function is called 🛑

that's it, that's the whole behavior. no cap. periodt 💅
