πŸ’– explain_setsockopt_or_die(3) πŸ’–

okay bestie, this one lives in the Library Functions Manual and it's about sockets, options, and refusing to fail quietly. let's get into it 🫢


✨ NAME ✨

explain_setsockopt_or_die β€” get and set options on sockets and report errors


🌸 SYNOPSIS 🌸

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

πŸ¦‹ DESCRIPTION πŸ¦‹

so basically, explain_setsockopt_or_die is your little ride-or-die wrapper around the setsockopt(2) system call. it does the thing, and if the thing fails, it prints a whole explanation to stderr β€” that explanation comes from explain_setsockopt(3) btw, iconic β€” and then it ends the process by calling exit(EXIT_FAILURE). no cap, it just exits. dramatic? yes. effective? also yes πŸ’…

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

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

here's the breakdown of every single one of those arguments, because we do not skip details in this house:

  • fildes β€” the fildes, exactly as to be passed to the setsockopt(2) system call.
  • level β€” the level, exactly as to be passed to the setsockopt(2) system call.
  • name β€” the name, exactly as to be passed to the setsockopt(2) system call.
  • data β€” the data, exactly as to be passed to the setsockopt(2) system call.
  • data_size β€” the data_size, exactly as to be passed to the setsockopt(2) system call.
Returns: this function only returns on success. on failure it prints an explanation and exits. that's the whole vibe. main character energy, no coming back 😭
