✨ explain_execve_or_die(3) ✨

okay bestie, welcome to the Library Functions Manual πŸŽ€ like yes it's a manual page but it's also a whole vibe, and this one's about explain_execve_or_die β€” the function that runs your program and, if things go sideways, tells you why before it dips. πŸ¦‹


🌸 NAME 🌸

explain_execve_or_die β€” execute program and report errors πŸ’…


✨ SYNOPSIS ✨

#include <libexplain/execve.h>
void explain_execve_or_die(const char *pathname, const char *const
*argv, const char *const *envp);

πŸ’– DESCRIPTION πŸ’–

so the explain_execve_or_die function is the one you call when you wanna hit up the execve(2) system call. and like, if it fails? bestie, it prints a whole explanation to stderr β€” courtesy of explain_execve(3) β€” and then the process literally ends itself by calling exit(EXIT_FAILURE). no cap. πŸ’€

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

explain_execve_or_die(pathname, argv, envp);

here's the rundown on the args, because we're thorough in this house 🫢

  • pathname β€” the pathname, exactly as to be passed to the execve(2) system call. no edits, no glow-ups, copy it over as-is. ✨
  • argv β€” the argv, exactly as to be passed to the execve(2) system call. again, verbatim, bestie. πŸ’…
  • envp β€” the envp, exactly as to be passed to the execve(2) system call. same energy, same exactness. 🌈

Returns:

this function only returns on success. on failure, it prints an explanation and exits. so if you ever see it come back, that's your sign that everything ate. πŸ‘‘
