explain_ferror_or_die(3)   Library Functions Manual   explain_ferror_or_die(3)

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  fol-
       lowing 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.
