💅 digital_start_poll(9) 💅

okay so bestie, we’re in the Kernel API Manual and this page is literally digital_start_poll(9) — it’s giving “kick off the poll” energy, no cap ✨

---

✨ NAME ✨

digital_start_poll — the start_poll operation, periodt 💅

---

🌸 SYNOPSIS 🌸

int digital_start_poll (struct nfc_dev *nfc_dev , __u32 im_protocols ,
__u32 tm_protocols );

---

🎀 ARGUMENTS 🎀

• nfc_dev — the device that’s getting polled, bestie 🫶
• im_protocols — a bitset of nfc initiator protocols to be used for polling ✨
• tm_protocols — a bitset of nfc transport protocols to be used for polling 🦋

---

🔥 DESCRIPTION 🔥

okay so here’s the vibe: for every supported protocol, the corresponding polling function gets added to the table of polling technologies (ddev->poll_techs[]) using digital_add_poll_tech 💖

and when a polling function fails — whether it’s by timeout or protocol error — the next one is schedule by digital_poll_next_tech on the poll workqueue (ddev->poll_work) 👑
