💖 explain_stime_or_die — Library Functions Manual 💖

okay so bestie, welcome to explain_stime_or_die(3) — it's the libexplain glow-up of stime(2), and it's giving "I will set your system time AND tell you exactly what went wrong" energy. no cap. ✨

🌸 NAME 🌸

explain_stime_or_die — set system time and report errors 🕰️💅

---

🎀 SYNOPSIS 🎀

#include <libexplain/stime.h>
void explain_stime_or_die(time_t *t);
int explain_stime_on_error(time_t *t);

literally just two functions, both iconic, both here to hold your hand while you talk to the kernel. 🫶

---

✨ DESCRIPTION ✨

so. explain_stime_or_die is the function you call when you want to call the stime(2) system call — but with ✨emotional support✨. if it fails, an explanation gets printed to stderr, and that explanation is obtained from the explain_stime(3) function. and then? the process terminates by calling exit(EXIT_FAILURE). yeah. it does not come back. it's done. it said what it said. 💀

and then there's explain_stime_on_error, the chiller sibling 🌈. it also calls the stime(2) system call, and on failure it also prints an explanation to stderr obtained from explain_stime(3) — but it still returns to the caller. no dramatic exit. just vibes and information. 😌

• t — the t, exactly as to be passed to the stime(2) system call. no notes. it's the t. you hand it over exactly like the syscall wants it. periodt. 💅

---

🦋 RETURN VALUE 🦋

explain_stime_or_die only returns on success — and honestly, for more deets on that, go see stime(2). on failure it prints an explanation and exits. it does not return. it is not coming back. it left the group chat. 😭

explain_stime_on_error always returns the value returned by the wrapped stime(2) system call. always. that's the whole bit. 🔥

---

🌈 EXAMPLE 🌈

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

explain_stime_or_die(t);

that's it. that's the example. chef's kiss. 👑
