💖 typec_partne...ster_altmode(9)

okay so bestie, welcome to the Kernel API Manual page for typec_partner_register_altmode — it's giving USB Type-C partner alternate-mode registration, and honestly the vibes are immaculate. periodt. ✨

🌸 NAME 🌸

typec_partner_register_altmode — Register USB Type-C Partner Alternate Mode

🎀 SYNOPSIS 🎀

struct typec_altmode * typec_partner_register_altmode (struct
       typec_partner *partner , const struct typec_altmode_desc *desc );

🦋 ARGUMENTS 🦋

• partner — USB Type-C Partner that supports the alternate mode. the device with the alt-mode tea. ☕
• desc — Description of the alternate mode. the little info card for the vibe. 💅

✨ DESCRIPTION ✨

so this routine is literally used to register each alternate mode individually that partner has listed in response to the Discover SVIDs command. no bundling, no skipping, bestie. 🫶

the modes for a SVID listed in response to the Discover Modes command need to be listed in an array in desc. yes, an array — in desc — that's the whole assignment. 📝

it returns a handle to the alternate mode on success, or ERR_PTR on failure. so: success = handle, failure = ERR_PTR, and that's the plot. 😭
