KLDNEXT(2)

💫 KLDNEXT(2) 💫

okay so this is kldnext(2), straight out of the System Calls Manual — we're doing kernel module list traversal today bestie, and honestly? it's giving tiny-but-mighty 🎀

🌸 NAME 🌸

kldnext — return the fileid of the next kld file

📚 LIBRARY 📚

Standard C Library (libc, -lc) — the classic, the icon, the one you already linked ✨

🦋 SYNOPSIS 🦋

#include <sys/linker.h>

int
kldnext(int fileid);

💖 DESCRIPTION 💖

so the kldnext() system call returns the fileid of the next kld file — like, the one right after fileid 👑 — or 0 if fileid is the last file loaded. periodt.

and here's the cute part: to get the fileid of the first kld file, you pass a fileid of 0 to kldnext(). that's your entry point, your main character moment, your "start here" arrow 🫶

🔥 RETURN VALUES 🔥

The kldnext() system call returns the fileid of the next kld file, or 0 if it's successful 😌

Otherwise kldnext() returns the value -1 and sets the global variable errno to indicate the error. not the vibe, but at least it tells you why 💀

🍓 ERRORS 🍓

The only error set by kldnext() is ENOENT — and that one shows up when fileid refers to a kld file that does not exist (i.e. is not loaded). so, like, it's not there. that's the whole thing 🙈
