explain_getcwd_or_die(3)

✨ NAME ✨

explain_getcwd_or_die — bestie, this one grabs your current working directory and spills the tea if something goes wrong 💖

It lives in explain_getcwd_or_die(3), in the Library Functions Manual. Okay so let's get into it 🫶

---

🌸 SYNOPSIS 🌸

#include <libexplain/getcwd.h>
void explain_getcwd_or_die(char *buf, size_t size);

Like… that's it. Two args. You got this 💅

---

🦋 DESCRIPTION 🦋

So the whole vibe of explain_getcwd_or_die is that it's a little wrapper that goes and calls the getcwd(2) system call for you. No cap. And if things go sideways? It doesn't just leave you hanging — it prints a whole explanation to stderr, sourced straight from explain_getcwd(3), and then it ends the whole process by calling exit(EXIT_FAILURE). Not me being dramatic, that's literally what it does 😭

It's designed to be dropped into your code in a fashion similar to this lil example right here:

explain_getcwd_or_die(buf, size);

Now let's talk about the parameters, because they matter:

• buf — this is the buf, exactly as to be passed to the getcwd(2) system call. Don't get cute with it, just pass it the same way 🎀
• size — and this is the size, exactly as to be passed to the getcwd(2) system call. Same energy, same value ✨

Returns:

Okay so here's the thing, and it's lowkey the most important part: this function only returns on success. That's it. That's the whole return situation. On failure it prints an explanation and exits — like, the process is gone. So don't be out here writing code that expects it to come back when something breaks, because it will not 🙈💀

Real talk: if you see this function return, congratulations, it worked. If it doesn't return, you're not debugging anymore, you're exiting. Periodt.
