explain_getw_or_die(3)	   Library Functions Manual	explain_getw_or_die(3)

NAME
       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);
