explain_getc_or_die - input of characters and report errors
int explain_getc_or_die(FILE *fp);
The explain_getc_or_die function is used to call the getc(3) system call. On failure an explanation will be printed to stderr, obtained from explain_getc(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
int c = explain_getc_or_die(fp);
