✨ explain_feof_or_die ✨

okay bestie, welcome to the explain_feof_or_die(3) page from the Library Functions Manual πŸ’– this is a libexplain thing, and it's genuinely so helpful it's giving main character energy.


🌸 NAME 🌸

explain_feof_or_die β€” check and reset stream status and report errors 🫢


πŸŽ€ SYNOPSIS πŸŽ€

#include <libexplain/feof.h>
void explain_feof_or_die(FILE *fp);
int explain_feof_on_error(FILE *fp);

πŸ’… DESCRIPTION πŸ’…

So. The explain_feof_or_die function is literally just there to call the feof(3) system call for you. But here's the twist: if it fails, an explanation gets printed to stderr, and that explanation comes from the explain_feof(3) function. And then? The process terminates by calling exit(EXIT_FAILURE). no cap, it's done, it's over, periodt πŸ’€

The explain_feof_on_error function is the chiller sibling. It also calls the feof(3) system call, and on failure it also prints an explanation to stderr (again, obtained from the explain_feof(3) function), but instead of dipping out it still returns to the caller. icon behavior honestly 🌈

  • fp β€” the fp, exactly as to be passed to the feof(3) system call. like, don't get creative with it, just hand it over the same way πŸŽ€

⭐ RETURN VALUE ⭐

The explain_feof_or_die function only returns on success β€” see feof(3) for more information. On failure it prints an explanation and exits, so it does not return. gone. bye. πŸ™ˆ

The explain_feof_on_error function always returns the value returned by the wrapped feof(3) system call. always. it's loyal like that πŸ’œ


πŸ”₯ EXAMPLE πŸ”₯

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

explain_feof_or_die(fp);

that's it. that's the whole vibe check. ✨
