explain_se...ame_or_die(3)

💖 NAME 💖

welcome to explain_se...ame_or_die(3), bestie 🫶 — this page is all about explain_setdomainname_or_die, aka set domain name and report errors. that's the whole vibe. set the name, and if it flops, you're gonna hear about it. periodt. 💅

---

✨ SYNOPSIS ✨

#include <libexplain/setdomainname.h>
void explain_setdomainname_or_die(const char *data, size_t data_size);
int explain_setdomainname_on_error(const char *data, size_t data_size);

---

🦋 DESCRIPTION 🦋

okay so. explain_setdomainname_or_die</p> is the function you call when you want to run the setdomainname(2) system call. and if that call fails? an explanation gets printed to stderr — courtesy of the explain_setdomainname(3) function, she's the one doing the explaining — and then the process literally terminates by calling exit(EXIT_FAILURE). no notes, no coming back, it's over. 😭

explain_setdomainname_on_error</p> is the softer sibling 🧚. she also calls the setdomainname(2) system call, and on failure she also prints an explanation to stderr, obtained from the explain_setdomainname(3) function — but then she still returns to the caller. she gives you a second chance. iconic behavior, honestly.

the arguments, because we do NOT skip the details here:

• data — the data, exactly as to be passed to the setdomainname(2) system call. no tweaking, no improvising, just pass it as-is.
• data_size — the data_size, exactly as to be passed to the setdomainname(2) system call. same energy. pass it exactly like that.

---

🔥 RETURN VALUE 🔥

explain_setdomainname_or_die</p> only returns on success — peek at setdomainname(2) if you want the full lore. on failure it prints an explanation and exits, so like… it does not return. at all. she left. 🚪💨

explain_setdomainname_on_error</p> always returns the value returned by the wrapped setdomainname(2) system call. always. she's reliable like that. 💜

---

🌸 EXAMPLE 🌸

the explain_setdomainname_or_die function is intended to be used in a fashion similar to the following example:

explain_setdomainname_or_die(data, data_size);

that's it, that's the moment. look at her go ✨
