vbg_misc_device_ioctl(9)

💅 NAME 💅

okay so bestie, this is the vbg_misc_device_ioctl(9) page from the Kernel API Manual ✨ and the name entry is literally:

vbg_misc_device_ioctl — Device I/O Control entry point. 🎀

That's the whole vibe: Device I/O Control entry point. Periodt.

✨ SYNOPSIS ✨

long vbg_misc_device_ioctl (struct file *filp , unsigned int req ,
unsigned long arg );

three inputs, one long return, and the function signature is copy-paste exact, iykyk 💖

🌸 ARGUMENTS 🌸

• filp — Associated file pointer. Yes, the associated file pointer, bestie 🫶
• req — The request specified to ioctl. That's the request you specified to ioctl ✨
• arg — The argument specified to ioctl. And that's the argument you specified to ioctl 💅

💖 RETURN 💖

0 on success, negated errno on failure. So success is 0, failure is negated errno — no cap, that's the return contract 🌈
