typec_register_plug(9)

💅 typec_register_plug(9) — like, the Kernel API Manual page, bestie

okay so picture this: it's the Linux kernel, it's the Kernel API Manual, and the function we're obsessing over today is typec_register_plug(9). yes that's a 9 in the parens, that means kernel API, we don't make the rules 🎀

---

✨ NAME ✨

typec_register_plug — register a USB Type-C Cable Plug. that's it, that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

struct typec_plug * typec_register_plug (struct typec_cable *cable ,
struct typec_plug_desc *desc );

two arguments, one cute little struct pointer coming back at you. slay. 💖

---

🎀 ARGUMENTS 🎀

• cable — the USB Type-C Cable that's got the plug on it. like, the plug's home cable, its main character context, yk?
• desc — the description of the cable plug. this is where you tell everyone what this plug actually is. ✨

---

👑 DESCRIPTION 👑

so this is the whole point of the page: typec_register_plug registers a device for the USB Type-C Cable Plug that's described in desc. 🫶

now, a USB Type-C Cable Plug represents a plug with electronics in it that can respond to USB Power Delivery SOP Prime or SOP Double Prime packages. like — it's not just a dumb chunk of metal, it's got chips, it's got opinions, it's got SOP Prime and SOP Double Prime energy going on. iykyk. ⚡

on success you get a handle to the cable plug back. on failure you get an ERR_PTR. which is the kernel way of being like "no 💀". check that thing, fr fr.
