mpt_event_register(9)

💅 mpt_event_register(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for mpt_event_register, and it's giving “protocol-specific event callback handler registration” energy. No cap. 💖

🌸 NAME 🌸

mpt_event_register — register protocol-specific event callback handler. That's the whole assignment, and it ate. ✨

🦋 SYNOPSIS 🦋

int mpt_event_register (u8 cb_idx , MPT_EVHANDLER ev_cbfunc );

🎀 ARGUMENTS 🎀

• cb_idx — the previously registered (via mpt_register) callback handle. Yes, that handle. 👑
• ev_cbfunc — the callback function itself, front and center. 💅

🔥 DESCRIPTION 🔥

okay so this routine can be called by one or more protocol-specific drivers if/when they choose to be notified of MPT events. That's the vibe: if you want the event tea, this is the registration situation. 🫶

It returns 0 for success. That's it — success is 0, and we love a clean little return value. ⭐
