OPTARG(3P)

💖 PROLOG 💖

Okay bestie, real talk before we even start: this manual page is part of the POSIX Programmer's Manual. That's the vibe.

But heads up — the Linux implementation of this interface may differ (so like, go consult the corresponding Linux manual page for details on Linux behavior, iykyk). Or, plot twist, the interface may not even be implemented on Linux at all. 🙈

✨ NAME ✨

optarg, opterr, optind, optopt — the options parsing variables. Yes, all four of them, one squad, no cap. 👑

🎀 SYNOPSIS 🎀

#include <unistd.h>

extern char *optarg;
extern int opterr, optind, optopt;

That's it. That's the whole declaration situation. So clean, so minimal, main character energy fr fr. 💅

🌸 DESCRIPTION 🌸

Okay so here's the thing — this page is literally just the variables. The actual lore? Refer to getopt().

That's the whole description. I know, I know, it's giving "and that's the tea" but for real, getopt() is where all the action happens. Go read that one, bestie. 🦋
