explain_ioctl_or_die(3)

💅 explain_ioctl_or_die — from the Library Functions Manual ✨

okay bestie, sit down, hydrate, and let me tell you about explain_ioctl_or_die(3) — she's a libexplain girlie and she does exactly what it says on the tin 🎀

---

🌸 NAME 🌸

explain_ioctl_or_die — control device and report errors 💖

---

✨ SYNOPSIS ✨

#include <libexplain/ioctl.h>
int explain_ioctl_or_die(int fildes, int request, void *data);

---

🦋 DESCRIPTION 🦋

so like. the explain_ioctl_or_die function is the one you call when you want to hit up the ioctl(2) system call, no cap. and if it fails? she does NOT leave you hanging. an explanation gets printed to stderr, sourced straight from explain_ioctl(3), and then the process ✨terminates✨ by calling exit(EXIT_FAILURE). dramatic? maybe. necessary? absolutely 💀

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

int result = explain_ioctl_or_die(fildes, request, data);

and here's the tea on the args, one by one:

• fildes — the fildes, exactly as to be passed to the ioctl(2) system call. no edits, no vibes-based reinterpretation, pass her through as-is 🫶
• request — the request, exactly as to be passed to the ioctl(2) system call. same deal 💅
• data — the data, exactly as to be passed to the ioctl(2) system call. you know the drill by now 😌

Returns:

this function only returns on success — see ioctl(2) for more information. on failure, she prints an explanation and exit()s. that's it, that's the whole return policy, main character energy only 👑

👑 SEE ALSO 👑

• ioctl(2) — control device
• explain_ioctl(3) — explain ioctl(2) errors
• exit(2) — terminate the calling process
