ipc_protocol_tq_msg_send(9)

💅 ipc_protocol_tq_msg_send — the kernel API manual, section 9, bestie 🎀

okay so real talk, we're in the kernel API manual (ipc_protocol_tq_msg_send(9)) and today's main character is a function that literally preps your msg and sends it to CP. that's the whole vibe. ✨

---

🌸 NAME 🌸

ipc_protocol_tq_msg_send — prepare the msg and send to CP 🫶

---

✨ SYNOPSIS ✨

int ipc_protocol_tq_msg_send (struct iosm_protocol *ipc_protocol , enum
ipc_msg_prep_type msg_type , union ipc_msg_prep_args *prep_args , struct
ipc_rsp *response );

like, that's the signature. it's giving "i take four things and i return an int" 💅

---

🦋 ARGUMENTS 🦋

• ipc_protocol — pointer to an ipc_protocol instance. your whole protocol situation lives here, bestie 💖
• msg_type — the message type. an enum ipc_msg_prep_type, ngl it tells the function what kind of msg we're dealing with 🔥
• prep_args — message arguments. a union ipc_msg_prep_args *, so it's the actual stuff going into the msg 🎀
• response — pointer to a response object which has a completion object and return code. yes, both. it's an icon, it does it all 👑

---

⭐ RETURN ⭐

0 on success, and a failure value on error. periodt. 💀

no cap, if you get anything other than 0 back, something went sideways — that's your failure value, go look at it.
