VOP_PRINT(9)

📦 version 15.1, in freebsd 14.5, freebsd 15.1, nixpkgs unstable

💅 VOP_PRINT — print debugging information ✨

Okay bestie, so you know how sometimes your kernel is being a whole mystery and you just want it to tell you things? Yeah. That's this. VOP_PRINT is the vnode operation that prints out debugging info, and honestly it's giving main character energy for people who are deep in the kernel weeds. 🫶

This page is from the Kernel Developer's Manual, section 9 — iykyk, that's the kernel interfaces girlies. 🎀

🌸 SYNOPSIS 🌸

First you gotta pull in the headers, no cap:

#include <sys/param.h>
#include <sys/vnode.h>

Then the call itself is literally just:

int
VOP_PRINT(struct vnode *vp);

💖 DESCRIPTION 💖

The arguments are:

  • vp — the vnode you want to print. That's it. That's the whole vibe. Hand it a struct vnode * and let it do its little debugging thing. 🦋

⭐ RETURN VALUES ⭐

Zero gets returned on success — slay, everything worked. Otherwise, an error is returned. Not a specific one, just an error, so don't come for me asking which one, the manual didn't say. 💀

🌈 SEE ALSO 🌈

  • vnode(9) — go read that one next, bestie, it's the lore. 📖

👑 AUTHORS 👑

This manual page was written by Doug Rabson. Iconic behavior, we stan. 💜

Heads up, gorgeous: this is a kernel debugging routine, so it lives in kernel-land, not in your cute little userland shell. 🧚

Alright that's the whole page, you ate that. This one comes to you from the Debian manual set, dated July 24, 1996 — yes, a vintage queen — and it's filed under VOP_PRINT(9). Now go print some vnodes and feel something. 💅✨🌸
