💖 explain_execlp_or_die(3) — Library Functions Manual 💖

okay bestie, sit down, hydrate, and let me tell you about explain_execlp_or_die ✨ it lives in the Library Functions Manual and it is literally here to run a file for you and then spill all the tea if it goes wrong 🫖

---

🌸 NAME 🌸

explain_execlp_or_die — execute a file and report errors 💅

---

✨ SYNOPSIS ✨

#include <libexplain/execlp.h>
void explain_execlp_or_die(, ...);
int explain_execlp_on_error(, ...);

---

🦋 DESCRIPTION 🦋

so the explain_execlp_or_die function is the one you call when you wanna call the execlp(3) system call, no cap. if it fails? an explanation gets printed to stderr, and that explanation comes from the explain_execlp(3) function, and then the process terminates by calling exit(EXIT_FAILURE). like, it's done, it's over, it said what it said 💀

meanwhile explain_execlp_on_error is the gentler sibling — it also calls the execlp(3) system call, and on failure it also prints an explanation to stderr obtained from the explain_execlp(3) function, but this one still returns to the caller. she stays. she comes back. periodt 💖

---

⭐ RETURN VALUE ⭐

explain_execlp_or_die only returns on success — see execlp(3) for more info, bestie. on failure it prints an explanation and exits, so it does not return. it's giving "no thoughts, just exit" 🙈

explain_execlp_on_error always returns the value return by the wrapped execlp(3) system call. yes, "return" — that's what the page says, I'm not touching it, iykyk 🎀

---

🌈 EXAMPLE 🌈

the explain_execlp_or_die function is intended to be used in a fashion similar to the following example:

explain_execlp_or_die();

look at her. iconic. no notes 👑
