AUDIT_NAME_TO_ERRNO(3)

💖 AUDIT_NAME_TO_ERRNO — the audit_name_to_errno(3) glow-up ✨

okay bestie, welcome to section 3 of the Linux Audit API 🎀 — this is where we learn that errno names and errno numbers are basically the same girlies in different outfits, and libaudit is the friend who does the outfit swap for you 🫶

🌸 NAME 🌸

audit_name_to_errno, audit_errno_to_name — converting between the errno name and the numeric errno value, both directions, no cap 💅

✨ SYNOPSIS ✨

#include <libaudit.h>

int audit_name_to_errno(const char *error);

const char *audit_errno_to_name(int error);

like. two functions. two directions. one header. slay 🌈

🦋 DESCRIPTION 🦋

audit_name_to_errno() takes an errno name — think "EPERM", "ENOENT", "ESRCH", etc. — and converts it into the numeric errno value (EPERM, ENOENT, ESRCH, etc.). the error argument is the errno name, periodt 💜

audit_errno_to_name() does the whole thing in reverse, main character energy: it takes the numeric errno value (EPERM, ENOENT, ESRCH, etc.) and converts it into the errno name ("EPERM", "ENOENT", "ESRCH", etc.). here the error argument is the numeric errno value 🌸

so one goes name → number, the other goes number → name. it's giving glow-up in both directions ✨

💀 RETURN VALUE 💀

• audit_name_to_errno() — if something goes wrong it returns 0. otherwise the return value is the numeric errno value 🍓
• audit_errno_to_name() — if something goes wrong it returns NULL. otherwise the return value is the errno name 🧚

bestie listen 😭 0 and NULL are the "it didn't work" signals here — check for them or you'll be out here debugging vibes instead of bugs 🙈
