pmcraid_setup_chrdev(9)

💖 pmcraid_setup_chrdev 💖

okay so bestie, welcome to the Kernel API Manual (section 9, the kernel-functions girly pop section) — today's main character is pmcraid_setup_chrdev, and honestly? she's the one who gets your adapter a name tag at the party 🎀

---

✨ NAME ✨

pmcraid_setup_chrdev — allocates a minor number and registers a char device 🦋

like, she grabs a minor number out of the pile and then goes "here, this character device is yours" and files the paperwork. slay.

---

🌸 SYNOPSIS 🌸

int pmcraid_setup_chrdev (struct pmcraid_instance *pinstance );

---

🎀 ARGUMENTS 🎀

• pinstance — pointer to the adapter instance for which to register the device 👑 lowkey the whole point: you're telling her which instance is getting this device registration.

---

💅 DESCRIPTION 💅

Return value 0 in case of success, otherwise non-zero.

that's it, that's the whole vibe check — 0 means she ate and everything's registered, anything else means something went sideways 😭 no further details given, so don't come for me, I'm just the messenger 🫶
