explain_getc_or_die(3)

💖 explain_getc_or_die — the manual page 💖

okay bestie, welcome to explain_getc_or_die(3), a lil library functions manual moment 🎀 this one's from libexplain and she is so helpful when you're reading characters and things go sideways.

---

✨ NAME ✨

explain_getc_or_die — input of characters and report errors 🦋

---

✨ SYNOPSIS ✨

#include <libexplain/getc.h>
int explain_getc_or_die(FILE *fp);

---

✨ DESCRIPTION ✨

so the tea is: the explain_getc_or_die function is there to call the getc(3) system call for you. 🫶

and if that call fails? bestie, it prints an explanation to stderr — that explanation comes from explain_getc(3) — and then it just terminates the whole process by calling exit(EXIT_FAILURE). dramatic? yes. effective? also yes. 💀

this function is meant to be used in a fashion similar to the following example:

int c = explain_getc_or_die(fp);

• fp — the fp, exactly as to be passed to the getc(3) system call. no funny business, pass it through as-is 💅

Returns:

• this function only returns on success — and when it does, it returns the next character or EOF at end of input. 🌸
• on failure, it prints an explanation and exits. that's it, that's the whole vibe. no coming back from that one 😭

✨ SEE ALSO ✨

• getc(3) — input of characters
• explain_getc(3) — explain getc(3) errors
• exit(2) — terminate the calling process
