EXPLAIN_GETSOCKOPT_OR_DIE(3)

💖 explain_getsockopt_or_die(3) 💖

okay bestie, welcome to the Library Functions Manual ✨ this one's a lil function from libexplain that's about to become your new emotional support syscall wrapper, no cap.

---

🌸 NAME 🌸

explain_getsockopt_or_die — get and set options on sockets and report errors 🫶

---

✨ SYNOPSIS ✨

#include <libexplain/getsockopt.h>
void explain_getsockopt_or_die(int fildes, int level, int name, void
*data, socklen_t *data_size);

---

🦋 DESCRIPTION 🦋

so the way that explain_getsockopt_or_die works is it calls the getsockopt(2) system call for you. and if that goes sideways? 😭 it prints a whole explanation to stderr — that explanation comes straight from explain_getsockopt(3) — and then it just ends the whole process by calling exit(EXIT_FAILURE). dramatic? yes. effective? also yes. periodt.

this function is meant to be used in a way that's similar to this example right here:

explain_getsockopt_or_die(fildes, level, name, data, data_size);

• fildes — the fildes, exactly as to be passed to the getsockopt(2) system call. like, literally the same value, don't get creative 💅
• level — the level, exactly as to be passed to the getsockopt(2) system call.
• name — the name, exactly as to be passed to the getsockopt(2) system call.
• data — the data, exactly as to be passed to the getsockopt(2) system call.
• data_size — the data_size, exactly as to be passed to the getsockopt(2) system call.

Returns:

this function only returns on success 🔥 on failure it prints an explanation and exits. so if you get your return value back, congrats, you ate. if you don't? you never will, bestie, because the process is gone 💀
