fixed_size_llseek(9)

✨ okay bestie, it's fixed_size_llseek(9) o'clock ✨

Welcome to the Kernel API Manual entry for fixed_size_llseek — literally the llseek implementation for fixed-sized devices, no cap. This is your group-chat recap where all the details stay cute and stay accurate. 💅

✨ NAME ✨

fixed_size_llseek — llseek implementation for fixed-sized devices. That's the whole name vibe, bestie. 🎀

🌸 SYNOPSIS 🌸

The signature is giving short-but-serious, so here it is exactly:

loff_t fixed_size_llseek (struct file *file , loff_t offset , int whence
       , loff_t size );

🎀 ARGUMENTS 🎀

• file — the struct file *file, aka the file structure to seek on. 🫶
• offset — the loff_t offset, aka the file offset to seek to. 🎯
• whence — the int whence, aka the type of seek. 🧭
• size — the loff_t size, aka the size of the file. 📏
