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

okay so real talk, we're deep in section 9 of the Kernel API Manual today, and the function on the slab is msg_to_mgmt_async — it sends a message to mgmt and does not wait around for a response. fire-and-forget energy, main character behavior, no cap 🫶

✨ NAME ✨

msg_to_mgmt_async — send message to mgmt without response 🌸

---

🎀 SYNOPSIS 🎀

int msg_to_mgmt_async (struct hinic_pf_to_mgmt *pf_to_mgmt , enum
hinic_mod_type mod , u8 cmd , u8 *buf_in , u16 in_size , enum
mgmt_direction_type direction , u16 resp_msg_id );

that's the whole signature, copied exactly, do not come for me 😭

🦋 ARGUMENTS 🦋

• pf_to_mgmt — the PF to MGMT channel, like the group chat you're posting into 💬
• mod — the module in the chip that will get the message, i.e. who's getting @'d 👀
• cmd — the command of the message, the actual thing you're asking for
• buf_in — the msg data, the payload, the content of your little text bubble 📩
• in_size — the msg data length, because we gotta know how big the bubble is
• direction — the direction of the original message, keeping track of which way things flow
• resp_msg_id — msg id to response for, so the reply knows where to land 🎯

🌈 DESCRIPTION 🌈

Return 0 - Success, negative - Failure — that's the whole vibe check, bestie. zero means slay, negative means it's giving flop 😭

also note: "async" is right there in the name fr fr — it sends and it does not sit there waiting for a response like some needy sync function 💀
