💅 ctucan_set_data_bittiming(9) — like, the CAN data bit timing setter, bestie

okay so this is a page from the Kernel API Manual (yes, section 9, the big-kid kernel section 🎀) and it's all about ctucan_set_data_bittiming — the routine that sets up the data bit timing for a CAN device. tiny page, but she's important ✨

---

🌸 NAME 🌸

ctucan_set_data_bittiming — the routine that handles CAN set data bit timing. that's it, that's the whole vibe 💅

---

✨ SYNOPSIS ✨

int ctucan_set_data_bittiming (struct net_device *ndev );

so she takes one arg and hands you back an int. icon behavior, no notes 🫶

---

🦋 ARGUMENTS 🦋

• ndev — a pointer to the net_device structure. literally just a pointer to your network device, that's the whole thing 🍓

---

🔥 RETURN 🔥

• 0 on success 🎉
• -EPERM on error 💀 (permission said no, bestie)
