iwpm_check_registration(9)

💅 iwpm_check_registration(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in kernel land, section 9 of the manual, and you just need to know if a client's registration matches the one you're holding. that's the whole vibe of iwpm_check_registration. let's get into it 🫶

---

✨ SYNOPSIS ✨

u32 iwpm_check_registration (u8 nl_client , u32 reg );

that's it. that's the whole call. two args, one u32 coming back at you. slay 💅

---

🌸 ARGUMENTS 🌸

• nl_client — the index of the netlink client 👑 like, which client are we even talking about? this tells you.
• reg — the given registration type you want to compare against 🎀 this is the thing we're checking for a match.

---

💖 DESCRIPTION 💖

so here's the tea: call iwpm_register_pid to register a client.

then this function does its little vibe check — it returns true if the client registration matches reg, and false otherwise. that's literally it, and honestly? iconic. no cap, it's a yes-or-no girlie and she knows it ✨

lowkey important: iwpm_register_pid is the one doing the registering here — don't skip that step and then act surprised, bestie 😭
