pmcraid_notify_ccn(9)

💖 pmcraid_notify_ccn — a whole kernel API manual moment 💖

okay so bestie, welcome to the pmcraid_notify_ccn(9) page, straight out of the Kernel API Manual ✨ this function's whole personality is: it notifies about CCN event msg to user space. that's it, that's the job, and it does it slayfully 🎀

🦋 NAME 🦋

pmcraid_notify_ccn — notifies about CCN event msg to user space 💅

no cap, that's the entire vibe. it takes a CCN event msg and makes sure user space hears about it, periodt.

---

🌸 SYNOPSIS 🌸

int pmcraid_notify_ccn (struct pmcraid_instance *pinstance );

---

🌈 ARGUMENTS 🌈

• pinstance — pointer adapter instance structure. literally just a pointer to the adapter instance struct, and yes she's required, she's the whole main character here 👑

---

⭐ DESCRIPTION ⭐

okay so here's the tea 🍓 — the description gives you the return value contract, and honestly it's short and sweet:

Return value: 0 if success, error value in case of any failure 💀

that's it. zero means she ate and everything went off without a hitch ✨ anything else is an error value and something went sideways. no extra lore, no hidden plot twists, iykyk.
