SendIocReset(9)

💅 SendIocReset(9) — like, the whole entire vibe

okay so bestie, we're in the Kernel API Manual today (yes, the kernel has a manual, and yes it's giving ✨documentation✨). This page is all about SendIocReset — a little function that slides a reset request over to your MPT adapter. No cap, that's the whole plot. 🎀

---

🌸 NAME

SendIocReset — slides an IOCReset request over to the MPT adapter, no drama, just vibes.

---

✨ SYNOPSIS

int SendIocReset (MPT_ADAPTER *ioc , u8 reset_type , int sleepFlag );

Like — three little args, one int coming back at you. She's simple, she's iconic, she ate. 💅

---

🫶 ARGUMENTS

• ioc — a pointer to the MPT_ADAPTER structure. That's your adapter bestie right there. 🦋
• reset_type — the reset type, and the expected values are literally MPI_FUNCTION_IOC_MESSAGE_UNIT_RESET or MPI_FUNCTION_IO_UNIT_RESET. Those two, exactly, no improvising. 🔥
• sleepFlag — this one just says whether the process can sleep. That's it, that's the whole job. 😴

---

👑 DESCRIPTION

So like — SendIocReset sends an IOCReset request to the MPT adapter. That's the tea. ☕

And when it's done it returns 0 for success, and non-zero for failure. That's your vibe check right there — zero means we slayed, anything else means something went sideways. 💀
