💖 ntb_register_client(9) 💖

okay bestie, welcome to the ntb_register_client page from the Kernel API Manual — yes it's a real section 9 manpage and yes it's lowkey iconic 🫶

✨ NAME ✨

ntb_register_client — the lil function that lets you register a client that's interested in ntb devices 👑

🌸 SYNOPSIS 🌸

ntb_register_client (client );

🎀 ARGUMENTS 🎀

  • client — your client context. that's the whole thing. it's giving "just hand me the pointer and let me cook" 💅

🦋 DESCRIPTION 🦋

so here's the vibe: your client gets added to the list of clients that are interested in ntb devices. slay. that's it, that's the list.

and then? the client gets notified about any ntb devices that are not already associated with a client — like, the lonely ones, the unclaimed ones, main character devices with no client energy 😭 — or if ntb devices get registered later. so basically you're signing up for "tell me about the devices, whenever they show up." fr fr. 📣

💀 RETURN 💀

Zero if the client is registered. Otherwise — an error number. (not me getting a nonzero back and having to deal with it 🙈)

🌈 SEE ALSO 🌈

source file lives at ./include/linux, and this whole icon was dated October 2026 — so yeah, it's from the future, iykyk 🧚‍♀️💫
