generic_file_llseek(9)

🎀 NAME 🎀

generic_file_llseek(9) — from the Kernel API Manual — is the generic llseek implementation for regular files. Yes bestie, regular files. 💅

✨ SYNOPSIS ✨

loff_t generic_file_llseek (struct file *file , loff_t offset , int
       whence );

🌸 ARGUMENTS 🌸

• file — the struct file *file situation: the file structure to seek on. Main character energy.
• offset — the file offset to seek to. Like, where you're trying to go.
• whence — the type of seek. That's the vibe of the seek, okay?

🦋 DESCRIPTION 🦋

Okay so this is a generic implementation of ->llseek, and it's useable for all normal local filesystems. No cap.

It just updates the file offset to the value specified by offset and whence. That's it. That's the whole slay. It's not doing extra side quests — just updating the offset. ✨
