wwan_register_ops(9)

💅 NAME 💅

wwan_register_ops — okay so this is the one that registers your WWAN device ops ✨

Yes bestie, it's the Kernel API Manual section 9, and it's lowkey iconic.

---

🎀 SYNOPSIS 🎀

int wwan_register_ops (struct device *parent , const struct wwan_ops *ops , void *ctxt , u32 def_link_id );

That's the whole vibe check right there, no cap 💖

---

🦋 ARGUMENTS 🦋

• parent — the device you're using as parent, and it's shared by every single WWAN port and every netdev that gets created. One parent, whole friend group 🫶
• ops — the operations you're registering. Like, the actual ops. Drop them here ✨
• ctxt — context that gets passed to the operations. Little backpack of stuff they carry around 🎒
• def_link_id — the id of the default link that the WWAN core is gonna automatically create for the WWAN device, no effort required from you 😌

⚠️ Important one, bestie: the default link will not be created if the value you pass is WWAN_NO_DEFAULT_LINK. That's the "actually never mind" option 💀

🌈 RETURN 🌈

0 on success — slay, we ate 🎉 a negative error code on failure — we do not talk about those 😭
