svc_register(9)

💅 svc_register — like, the Kernel API Manual entry, bestie ✨

Okay so real talk, this is a page from the Kernel API Manual (svc_register(9), section 9, the kernel-functions girlies) and it's lowkey short but it ate. Let's get into it 🎀

---

✨ NAME ✨

svc_register — register an RPC service with the local portmapper 🫶

---

🌸 SYNOPSIS 🌸

int svc_register (const struct svc_serv *serv , struct net *net , const
       int family , const unsigned short proto , const unsigned short port );

It returns an int, bestie. That's the whole vibe check. 💜

---

🦋 ARGUMENTS 🦋

• serv — the svc_serv struct for the service you're registering. Like, the actual service object itself, main character energy 👑
• net — the net namespace for the service to register. Yes, namespace. Not me forgetting namespaces exist 🙈
• family — protocol family of the service's listener socket. So like, the family your listener is repping 🌈
• proto — transport protocol number to advertise. A number, okurrr, not a name — a number 🔥
• port — port to advertise. That's it, that's the whole thing 💅

---

💖 DESCRIPTION 💖

Here's the tea: the service gets registered for any address in the passed-in protocol family. That's literally the description. Short and iconic, no notes ⭐

So like, whenever you hand over family, you're signing up the service for every address in that protocol family — not one specific address, not a little range, any address in it. Slay 💫
