💅 gfs2_llseek(9) — seek to a location in a file 💅

okay bestie, welcome to the Kernel API Manual entry for gfs2_llseek(9). This is the little function that handles seeking to a location in a file, and we're gonna get into every detail together. 🫶

🎀 NAME 🎀

gfs2_llseek — seek to a location in a file

✨ SYNOPSIS ✨

loff_t gfs2_llseek (struct file *file , loff_t offset , int whence );

🦋 ARGUMENTS 🦋

• file — the file, literally the file we're working with.
• offset — the offset, periodt.
• whence — where to seek from: SEEK_SET, SEEK_CUR, or SEEK_END. 👑

🌸 DESCRIPTION 🌸

When whence is SEEK_END, this requires the glock for the file, because it references the file's size. No cap, that's the whole description vibe. 💅

⭐ RETURN ⭐

The new offset, or errno. That's it, bestie — the new offset or errno. 🫶
