✨ nic_mgmt_msg_handler 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the deep kernel-lore part of the group chat now 🫶 this one's all about nic_mgmt_msg_handler, the nic mgmt event handler. it's giving "short signature, whole lotta responsibility" energy and honestly? iconic 👑

---

🌸 NAME 🌸

nic_mgmt_msg_handler — the nic mgmt event handler fr fr 💖

---

🎀 SYNOPSIS 🎀

no cap, here's the whole vibe — copy it exactly, don't @ me:

void nic_mgmt_msg_handler (void *handle , u8 cmd , void *buf_in , u16
in_size , void *buf_out , u16 *out_size );

---

🦋 ARGUMENTS 🦋

six args, six little besties, each one carrying its own luggage ✨

• handle — the private data for the handler. it's the handler's own personal stash, iykyk 🙈
• cmd — the message command. this is the u8 that tells everyone what we're doing here 💅
• buf_in — the input buffer. stuff comes in here 🍓
• in_size — the input size. so we know how much of that input buffer is actually real, periodt
• buf_out — the output buffer. stuff goes out here 🌈
• out_size — the returned output size. lowkey a pointer, so it can hand the size back to you 👑
