sock_from_file(9)

✨ NAME ✨

okay bestie, welcome to sock_from_file(9) from the Kernel API Manual 💖 — she’s lowkey tiny but highkey iconic. The official name line is:

• sock_from_file — Return the &socket bounded to @file.

No cap, that’s the exact name description. Slay.

✨ SYNOPSIS ✨

struct socket * sock_from_file (struct file *file );

That’s the whole signature, bestie. Copy it exactly, don’t get creative with the spacing 💅.

🎀 ARGUMENTS 🎀

• file — file 🙈 (yes, the entire argument description is literally just file; I am not inventing extra lore, periodt).

💅 DESCRIPTION 💅

On failure returns NULL. That’s the whole description, queen — no extra behavior spelled out here, so I’m not gonna make one up. If it fails, you get NULL; that’s the vibe check 😭.

🦋 SEE ALSO 🦋
