ipc_protocol_dl_td_prepare(9)

💖 ipc_protocol_dl_td_prepare 💖

okay bestie, so this one lives in the Kernel API Manual, section 9, and it's literally called ipc_protocol_dl_td_prepare. No cap, that's the whole name. Let's get into it. 🎀

---

✨ NAME ✨

ipc_protocol_dl_td_prepare — the function for providing DL TDs to CP. That's it, that's the job. 🫶

---

✨ SYNOPSIS ✨

bool ipc_protocol_dl_td_prepare (struct iosm_protocol *ipc_protocol ,
struct ipc_pipe *pipe );

Look at the signature, she's giving very official. Returns a bool, takes two pointers, and yes the spacing is exactly like that — don't come for me, I don't make the rules. 💅

---

✨ ARGUMENTS ✨

• ipc_protocol — your iosm_protocol instance, the main character of this whole operation 👑
• pipe — the pipe instance, aka the other main character 🌸

---

✨ RETURN ✨

• true in success 🎉
• false in case of error 😭

Literally that simple. Binary. Iconic. Periodt.
