explain_creat_or_die(3)

✨ explain_creat_or_die — like, the manual page for it ✨

okay bestie, welcome to the libexplain section 3 glow-up 🎀 this one is explain_creat_or_die(3) and she is very much the "do the thing or else" girlie of the creat world 💅

---

💖 NAME 💖

explain_creat_or_die — create and open a file with creat, and if it goes sideways? she reports the errors and dips. no cap. 😭

---

🌸 SYNOPSIS 🌸

#include <libexplain/creat.h>
void explain_creat_or_die(const char *pathname, int mode);

like, that's the whole vibe. two arguments, one function, zero chill 🦋

---

🫶 DESCRIPTION 🫶

so explain_creat_or_die is the function you call when you want to hit up the creat(2) system call, but you also want a bestie who explains things when it all falls apart. 💀

if it fails, an explanation gets printed to stderr — and that explanation comes straight from explain_creat(3) — and then the process terminates by calling exit(EXIT_FAILURE). she does not stick around for the aftermath, periodt. ✨

this function is meant to be used in a fashion similar to this little example here:

explain_creat_or_die(pathname, mode);

and now the deets on the arguments, because we love a labeled moment 👑

• pathname — the pathname, exactly as to be passed</> to the creat(2) system call. like, don't get cute with it, pass it exactly. 🙈
• mode — the mode, exactly as to be passed</> to the creat(2) system call. same energy, same rule. 💜

Returns:

this function only returns on success. on failure, it prints an explanation and exits. that's it, that's the whole return policy, no refunds, no exchanges 🎀

lowkey important: there is no "on error" branch for you to handle. she handles it. by leaving. 💅

🌈 SEE ALSO 🌈

• creat(2) — open and possibly create a file or device 🍓
• explain_creat(3) — explain creat(2) errors (the source of the gossip) 🔥
• exit(2) — terminate the calling process (the dramatic exit itself) 👑
