NAME

       explain_ferror_or_die - check stream status and report errors

SYNOPSIS

       #include <libexplain/ferror.h>
       void explain_ferror_or_die(FILE *fp);

DESCRIPTION

       The explain_ferror_or_die function is used to call the ferror(3) system
       call.  On failure an explanation will be printed  to  stderr,  obtained
       from  explain_ferror(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:
              explain_ferror_or_die(fp);

       It  is  essential that this function cal be placed as close as possible
       to the I/O code that has caused the problem, otherwise intervening code
       could have altered the errno global variable.

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

       Returns:
               This  function  only returns on success.  On failure, prints an
               explanation and exits.
