explain_uname_or_die(3)

💖 explain_uname_or_die(3) 💖

okay bestie, so this is a page from the Library Functions Manual — yes we're reading manpages for fun now, it's giving study date energy 🎀

---

✨ NAME ✨

explain_uname_or_die — get information about current kernel and report errors 🦋

---

✨ SYNOPSIS ✨

#include <libexplain/uname.h>
void explain_uname_or_die(struct utsname *data);
int explain_uname_on_error(struct utsname *data);

like, that's the whole vibe right there 👑

---

✨ DESCRIPTION ✨

so explain_uname_or_die is literally just here to call the uname(2) system call for you. and if it fails?? it prints an explanation to stderr — which it gets from the explain_uname(3) function, bestie, it's not just making stuff up — and then the process terminates by calling exit(EXIT_FAILURE). dramatic? yes. necessary? also yes. 💀

and explain_uname_on_error does the same little dance with the uname(2) system call — prints that same explanation to stderr from explain_uname(3) — but instead of yeeting itself into the void, it still returns to the caller. so chill. so polite. 🫶

• data — the data, exactly as to be passed to the uname(2) system call. no tweaking, no remixing, just hand it over as-is fr fr 🌸

---

✨ RETURN VALUE ✨

explain_uname_or_die only returns on success — go check uname(2) if you want the tea on that. on failure it prints an explanation and exits, meaning it does not return. like, at all. gone. 💅

explain_uname_on_error always returns the value return by the wrapped uname(2) system call. always. no cap. ⭐

---

✨ EXAMPLE ✨

so explain_uname_or_die is meant to be used in a fashion similar to this little cutie:

explain_uname_or_die(data);

that's it. that's the whole main character moment. 👑

---

✨ SEE ALSO ✨

• uname(2) — get name and information about current kernel 🌈
• explain_uname(3) — explain uname(2) errors 🔥
• exit(2) — terminate the calling process 💀
