pmcraid_ioctl_driver(9)

🌸 NAME 🌸

okay bestie, welcome to pmcraid_ioctl_driver(9) — straight out of the Kernel API Manual, and it's literally the ioctl handler for commands handled by the driver itself. No cap, that's the whole assignment: the driver is handling its own business. 💅

✨ SYNOPSIS ✨

long pmcraid_ioctl_driver (struct pmcraid_instance *pinstance , unsigned
int cmd , unsigned int buflen , void __user *user_buffer );

🎀 ARGUMENTS 🎀

• pinstance — pointer to the adapter instance structure, the main-character adapter vibe. 👑
• cmd — the ioctl command passed in. periodt.
• buflen — length of user_buffer.
• user_buffer — user buffer pointer. 🫶

💅 DESCRIPTION 💅

Return Value 0 in case of success, otherwise appropriate error code. That's the tea — success gets you a 0, and anything else gives you the appropriate error code. fr fr. 😭
