✨ genlmsg_new — the Kernel API Manual moment 💅

okay so bestie, welcome to genlmsg_new from the Kernel API Manual 🎀 this one is a kernel function, and honestly? it's giving "let me just allocate a brand new generic netlink message for you, bestie" energy ✨

🌸 NAME 🌸

genlmsg_new — allocate a new generic netlink message 🦋

like, it's literally the function that spins up a fresh generic netlink message for you. no cap.

---

💖 SYNOPSIS 💖

struct sk_buff * genlmsg_new (size_t payload , gfp_t flags );

look at her. struct sk_buff * is what you get back — a pointer to a socket buffer 💅 and she takes two arguments: payload and flags. iconic signature, honestly.

---

🫶 ARGUMENTS 🫶

• size_t payload — this is the size of the message payload 🍓 like, how much message you actually want in there. that's the number you're working with, bestie.
• gfp_t flags — the type of memory to allocate 🌈 yes, the memory allocation flags. that's the whole vibe of this one — it tells the allocator how you want that memory handled. ngl, very important.
