✨ NAME ✨

explain_fgetc_or_die — input of characters and report errors

---

🌸 SYNOPSIS 🌸

#include <libexplain/fgetc.h>
int explain_fgetc_or_die(FILE *fp);

---

💅 DESCRIPTION 💅

So explain_fgetc_or_die is the function you call when you wanna call the fgetc(3) system call, but you also want receipts if it goes wrong. If it fails, an explanation gets printed to stderr — and that explanation comes straight from explain_fgetc(3) — and then the process terminates by calling exit(EXIT_FAILURE). yes bestie, it's giving dramatic exit, but make it informative. 💀

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

int c = explain_fgetc_or_die(fp);

• fp — the fp, exactly as to be passed to the fgetc(3) system call. like, don't get creative with it, just hand it over the same way. 🫶

Returns:

This function only returns on success. On failure, prints an explanation and exits. that's it, that's the whole deal — she does not come back to tell you what happened, she tells you what happened on her way out the door. 😭
