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.
