KLDFIRSTMOD(2)

okay so bestie, we're in the System Calls Manual, and this page is KLDFIRSTMOD(2). no cap, it's a tiny syscall page but it's lowkey important if you're messing with kld stuff. 💅

🌸 NAME 🌸

kldfirstmod — return the first module id from the kld file you specified. periodt. 🦋

📚 LIBRARY 📚

this one comes from the Standard C Library, aka libc, and you link it with -lc. so iconic. ✨

✨ SYNOPSIS ✨

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

int
kldfirstmod(int fileid);

💖 DESCRIPTION 💖

so kldfirstmod() is a system call. it returns the module id pertaining to the first module referenced by fileid. that's the whole vibe. if fileid points at a kld file, you get the id of the first module it references. 🎀

🫶 RETURN VALUES 🫶

kldfirstmod() will return the id of the first module referenced by fileid, or 0 if there are no references. so if it's empty, you get a lil 0. no references, no drama. 💀

😭 ERRORS 😭

• [ENOENT] — the kld file referenced by fileid was not found. literally not there. poof. 🙈
