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.

SEE ALSO

	       explain ferror(3) errors

	      FILE *fp = explain_fdopen_or_die(fd, mode);

       fd      The fd, exactly as to be passed to the fdopen(3) system call.

       mode    The mode, exactly as to be passed to the fdopen(3) system call.
