explain_fchdir_or_die(3)

💖 explain_fchdir_or_die — NAME ✨

okay bestie, listen up: explain_fchdir_or_die is literally the function that changes your directory and then reports any errors like the drama queen it is. this page lives in section 3 of the Library Functions Manual, and it's giving "tiny function, huge personality." 💅

---

🎀 SYNOPSIS 🎀

no thoughts, just vibes and this exact code:

#include <libexplian/fchdir.h>
void explain_fchdir_or_die(int fildes);

(and yes, libexplian is spelled exactly like that, don't come for me, i'm just the messenger 🫶)

---

🌸 DESCRIPTION 🌸

so the explain_fchdir_or_die function is here to change directory by way of the fchdir(2) system call. that's its whole job. its moment. its main character era. ✨

and when it fails? oh it does NOT go quietly. it prints an error message on stderr via explain_fchdir(3), and then it exits. periodt. no second chances, no redemption arc, we're done here 💀

this function is meant to be used in a fashion similar to the following example — literally just like this:

explain_fchdir_or_die(fildes);

and about that argument:

• fildes — exactly as to be passed to the fchdir(2) system call. like, word for word, don't get creative with it bestie 🌈
