explain_unlink_or_die(3)

💖 explain_unlink_or_die(3) 💖

okay bestie, so you found a page from the Library Functions Manual and it's literally about deleting files and not pretending everything's fine when it goes wrong. iconic behaviour, honestly. let's get into it 🦋

✨ NAME ✨

explain_unlink_or_die — delete a file and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/unlink.h>
void explain_unlink_or_die(const char *pathname);

---

🎀 DESCRIPTION 🎀

okay so explain_unlink_or_die is the function you call when you want to hit up the unlink(2) system call, but you also want someone to explain what went wrong if it fails. and by someone, i mean it prints an explanation to stderr, grabbed straight from explain_unlink(3), and then the process just… ends it. by calling exit(EXIT_FAILURE). no notes, no coming back. 💀

this function is meant to be used in a fashion similar to the following example:

explain_unlink_or_die(pathname);

pathname

• the pathname, exactly as to be passed to the unlink(2) system call. like, exactly exactly. don't get cute with it. 🌈

Returns:

• this function only returns on success. on failure, it prints an explanation and exits. that's the whole deal. main character energy, no second chances. 👑

---

👑 SEE ALSO 👑

• unlink(2) — delete a name and possibly the file it refers to
• explain_unlink(3) — explain unlink(2) errors
• exit(2) — terminate the calling process
