💖 explain_getaddrinfo_or_die — Library Functions Manual 💖

okay bestie, sit down, hydrate, and let me tell you about the little libexplain function that does your network address translation AND reads the receipts when it goes wrong 🫶

---

✨ NAME ✨

explain_getaddrinfo_or_die — network address translation and report errors

---

🌸 SYNOPSIS 🌸

#include <libexplain/getaddrinfo.h>
void explain_getaddrinfo_or_die(const char *node, const char *service,
       const struct addrinfo *hints, struct addrinfo **res);

---

🦋 DESCRIPTION 🦋

so the explain_getaddrinfo_or_die function is basically a glow-up wrapper around the getaddrinfo(3) system call. it calls it for you. and if it fails? it prints an explanation to stderr — and that explanation comes straight from explain_getaddrinfo(3) — and then the process terminates by calling exit(EXIT_FAILURE). like. it does not come back. it's giving main character exit 😭

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

explain_getaddrinfo_or_die(node, service, hints, res);

here's what all the little guys mean:

• node — the node, exactly as to be passed to the getaddrinfo(3) system call. no notes, no edits, exactly as-is 💅
• service — the service, exactly as to be passed to the getaddrinfo(3) system call. same energy, exactly as-is ✨
• hints — the hints, exactly as to be passed to the getaddrinfo(3) system call. exactly as-is, bestie, do not freestyle 🎀
• res — the res, exactly as to be passed to the getaddrinfo(3) system call. you guessed it: exactly as-is 🌈

Returns:

This function only returns on success. On failure, prints an explanation and exits.

bestie fr fr: this function only returns on success. on failure it prints an explanation and exits. so if you're waiting for it to come back with bad news, it won't — it's gone 💀
