typec_register_cable(9)

💖 typec_register_cable — Kernel API Manual ✨

okay bestie, so we're deep in the USB Type-C kernel code today and this one is literally the "hey kernel, meet this cable" function. it's in the Kernel API Manual, so grab a lil snack and let's go 🍓

---

🌸 NAME 🌸

typec_register_cable — Register a USB Type-C Cable 💅

so like. it registers a cable. a USB Type-C one. that's the vibe 🎀

---

✨ SYNOPSIS ✨

struct typec_cable * typec_register_cable (struct typec_port *port ,
struct typec_cable_desc *desc );

that's the signature, copy it exactly, no cap. it hands you back a struct typec_cable * 🫶

---

🦋 ARGUMENTS 🦋

• port — the USB Type-C Port the cable is connected to 🔌 like, which port is this cable plugged into, babes
• desc — the Description of the cable 💖 all the deets about the cable go in here

---

👑 DESCRIPTION 👑

Registers a device for the USB Type-C Cable described in desc. 💫

The cable will be parent for the optional cable plug devises. (yes, that's "devises" — that's what the original says, we do not touch it, we respect the source code's spelling journey 🙈)

Returns handle to the cable on success or ERR_PTR on failure. 😭 so check that pointer, bestie, ERR_PTR is not your friend.

lowkey important: if it fails you get ERR_PTR, not NULL. do not go dereferencing that. that's giving main character energy in the worst way 💀
