✨ NAME ✨

okay so bestie, this page is issei_cl_connect(9) from the Kernel API Manual, and it’s literally the matchmaker function for FW and host clients. No cap. 🫶

🛰️ SYNOPSIS 🛰️

Here’s the exact signature, character-for-character, because we do not mess with source code in this group chat:

       int issei_cl_connect (struct issei_host_client *cl , const uuid_t *uuid
       , u32 *mtu , u8 *ver , u32 *flags );

---

🎀 ARGUMENTS 🎀

• cl — host client. the host-side bestie getting connected 🫶
• uuid — FW client unique ID. the special little name tag for the firmware client ✨
• mtu — memory for FW client max message size. this is the memory spot for that max message size 💾
• ver — memory for FW client version. memory for the FW client version, periodt 🏷️
• flags — memory for FW client flags. memory for the FW client flags, no extras 🚩

---

💫 DESCRIPTION 💫

It searches for the firmware client by UUID and connects it to the provided host client — but only if it’s not already connected to some client. That’s the whole vibe: find by UUID, hook it up, don’t double-book. 💅
