genl_register_family(9)

📦 version 7.3.1, in nixpkgs unstable

okay so welcome to the Kernel API Manual, bestie 💅 this is the page for genl_register_family, and it's literally the function that registers a generic netlink family. group-chat summary: it validates the family first, then registers it. slay.

🌸 NAME 🌸

genl_register_family — register a generic netlink family ✨

🎀 SYNOPSIS 🎀

int genl_register_family (struct genl_family *family );

🦋 ARGUMENTS 🦋

  • family — the generic netlink family 👑 that's the whole vibe of this argument, no cap.

💖 DESCRIPTION 💖

So the way this works is: genl_register_family registers the specified family after validating it first. validation first, registration second — main character energy, honestly.

⚠️ Only one family may be registered with the same family name or identifier. that's the rule, bestie, and it is not flexible. one name, one identifier, periodt. 💀

The family's ops, multicast groups, and module pointer must already be assigned. like, all set up before this function does its thing — don't come in with those missing, fr fr.

Return 0 on success or a negative error code. that's it. iconic. 🌈
