tb_domain_alloc(9)

🌸 NAME 🌸

tb_domain_alloc(9) — from the Kernel API Manual — is the “Allocate a domain” function, bestie. That's the whole name vibe: it allocates a domain. 💅✨

🦋 SYNOPSIS 🦋

struct tb * tb_domain_alloc (struct tb_nhi *nhi , int timeout_msec ,
size_t privsize );

🎀 ARGUMENTS 🎀

• nhi — pointer to the host controller. Literally the host-controller pointer, no cap. 🫶
• timeout_msec — the control channel timeout for non-raw messages. Exact scope, exact vibe. ⏱️
• privsize — size of the connection manager private data. It's giving “how big is the private data,” periodt. 💖

✨ DESCRIPTION ✨

This one allocates and initializes a new Thunderbolt domain. ✨ Connection managers are expected to call this and then fill in cm_ops accordingly — that's the follow-up step, iykyk. 🫶

Bestie caveat: call tb_domain_put to release the domain before it has been added to the system. Do not skip this, fr fr. 💀

🌈 RETURN 🌈

Pointer to struct tb, or NULL in case of error. That's the whole return glow-up — pointer or NULL, no extra lore. 👑
