mpi3mr_memset_buffers(9)

💖 NAME 💖

okay so bestie, this is mpi3mr_memset_buffers(9) from the Kernel API Manual — manual name folded in right here at the top — and its whole name-card vibe is memset memory for a controller. iconic, honestly. 💅

---

✨ SYNOPSIS ✨

The signature is literally this, character for character:

void mpi3mr_memset_buffers (struct mpi3mr_ioc *mrioc );

---

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. That’s the controller you’re doing the memory-clearing for, bestie. 🫶

---

🌸 DESCRIPTION 🌸

This one clears all the memory allocated for a controller. The typical call is post reset, so the memory allocated during the controller init can be reused. That’s the whole plot — no extra lore, no surprise side quest. 🌈✨

---

💜 RETURN 💜

Nothing. Literally nothing comes back. The page says Nothing., and it means it, no cap. 💀
