STRUCT HBM_NOTIFICATION_RESPONSE(9)

💅 NAME 💅

struct hbm_notification_response — the response that starts/stops a notification, bestie. That's literally it.

✨ SYNOPSIS ✨

Okay so here's the whole struct, no cap, copy-paste this into your brain:

struct hbm_notification_response {
    u8 hbm_cmd;
    u8 me_addr;
    u8 host_addr;
    u8 status;
    u8 start;
    u8 reserved[3];
 };

🎀 Members 🎀

• hbm_cmd — the bus message command header. it's giving "hi, I'm the header" energy 🫶
• me_addr — the address of the client in ME. yes, that ME. slay.
• host_addr — the address of the client in the driver ✨
• status — this one's a (mei_hbm_status) and it's the response status for the request. vibe check time, here's the whole squad:
  • MEI_HBMS_SUCCESS — a successful stop/start, we love to see it 💖
  • MEI_HBMS_CLIENT_NOT_FOUND — if the connection could not be found 😭 awkward
  • MEI_HBMS_ALREADY_STARTED — for start requests for a previously started notification (girl, we already did this one 💀)
  • MEI_HBMS_NOT_STARTED — for a stop request, for a connected client for whom asynchronous notifications are currently disabled 🙈
• start — literally the whole mood: start = 1 for start, stop = 0 for stop, of asynchronous notifications 👑
• reserved — reserved. it's reserved. don't touch it 🎀
