genlmsg_msg_size(9)

🎀 NAME 🎀

genlmsg_msg_size — length of genetlink message not including padding.

Okay so this is the genlmsg_msg_size(9) page from the Kernel API Manual, and it's giving “tiny but important helper” energy. 💅 It's about the length of a genetlink message, and the key detail is not including padding — padding does not count, no cap. ✨

✨ SYNOPSIS ✨

int genlmsg_msg_size (int payload );

Bestie, that's the whole signature — one int payload argument, and yes, keep the spacing exactly like that. Copy it character for character. 🫶

🌸 ARGUMENTS 🌸

• payload — length of message payload

That's the only argument, and it's literally just the message payload length. Iconic, low-effort, useful. 🍓
