       explain_getw_or_die - input a word (int) and report errors

SYNOPSIS

       #include <libexplain/getw.h>
       int explain_getw_or_die(FILE *fp);
       int explain_getw_on_error(FILE *fp);

DESCRIPTION

       The  explain_getw_or_die function is used to call the getw(3) system call. On failure an explanation will
       be printed to stderr, obtained from the explain_getw(3) function, and  then  the  process  terminates  by
       calling exit(EXIT_FAILURE).

       The  explain_getw_on_error  function  is  used to call the getw(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_getw(3) function, but still returns to the caller.

       fp      The fp, exactly as to be passed to the getw(3) system call.

RETURN VALUE

       The explain_getw_or_die function only returns on success, see getw(3) for more information.  On  failure,
       prints an explanation and exits, it does not return.

       The explain_getw_on_error function always returns the value return by the wrapped getw(3) system call.

EXAMPLE

       The explain_getw_or_die function is intended to be used in a fashion similar to the following example:
              int result = explain_getw_or_die(fp);
