explain_accept_or_die(3)

💖 explain_accept_or_die(3) 💖

okay bestie, so this one lives in the Library Functions Manual, and it's literally called explain_accept_or_die — yeah the name is dramatic but she earns it, i promise 🫶

---

✨ NAME ✨

explain_accept_or_die — accept a connection on a socket and report errors 🌸

---

🦋 SYNOPSIS 🦋

#include <libexplain/accept.h>
int explain_accept_or_die(int fildes, struct sockaddr *sock_addr,
socklen_t *sock_addr_size);

---

👑 DESCRIPTION 👑

so the explain_accept_or_die function is what you call when you wanna call the accept(2) system call, but you're not about to be left on read if it goes wrong. if it fails, an explanation gets printed to stderr — and that explanation comes straight from explain_accept(3) — and then the process terminates by calling exit(EXIT_FAILURE). no cap. it literally dies 💀

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

int fd = explain_accept_or_die(fildes, sock_addr, sock_addr_size);

• fildes — the fildes, exactly as to be passed to the accept(2) system call. no notes, pass it through as-is 💅
• sock_addr — the sock_addr, exactly as to be passed to the accept(2) system call. same energy ✨
• sock_addr_size — the sock_addr_size, exactly as to be passed to the accept(2) system call. yep, also verbatim 🎀

Returns:

• this function only returns on success — see accept(2) for more information. on failure, it prints an explanation and exits. that's it, that's the whole deal 🧚

🌈 SEE ALSO 🌈

• accept(2) — accept a connection on a socket
• explain_accept(3) — explain accept(2) errors
