💖 explain_fclose_or_die(3) 💖

okay bestie, welcome to the Library Functions Manual section of the group chat — today we're talking about explain_fclose_or_die, and no, the name is not a threat, it's a lifestyle 🫶

✨ NAME ✨

explain_fclose_or_die — close a stream and report errors 🌊

---

✨ SYNOPSIS ✨

#include <libexplain/fclose.h>
void explain_fclose_or_die(FILE *fp);

---

✨ DESCRIPTION ✨

so here's the tea ☕ — the explain_fclose_or_die function is used to fflush(3) and fclose(3) the given stream. that's it, that's the job, she's a closer 💅

but if there is an error? she does NOT let it slide, bestie. it will be reported using explain_fclose(3), and then she terminates by calling exit(EXIT_FAILURE). dramatic exit, absolutely iconic, no notes 😭

explain_fclose_or_die(fp);

• fp — the fp, exactly as to be passed to the fclose(3) system call. like, the exact same one, don't get creative with it 🎀

Returns:

• Only returns on success. 🌸 Reports error and process exits on failure. 💀 so like, if she comes back at all, that's a win. if she doesn't come back... that was the plan, ngl.
