NAME

explain_getc_or_die - input of characters and report errors

SYNOPSIS

#include <libexplain/getc.h>

int explain_getc_or_die(FILE *fp);

DESCRIPTION

This function is intended 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.

Returns:

This function only returns on success, and returns the next character or EOF at end of input. On failure, prints an explanation and exits.
