explain_fseek_or_die(3)	   Library Functions Manual    explain_fseek_or_die(3)

NAME
       explain_fseek_or_die - reposition a stream and report errors

SYNOPSIS
       #include	<libexplain/fseek.h>
       void explain_fseek_or_die(FILE *fp, long	offset,	int whence);
       int explain_fseek_on_error(FILE *fp, long offset, int whence);

DESCRIPTION
       The  explain_fseek_or_die  function is used to call the fseek(3)	system
       call. On	failure	an explanation will be	printed	 to  stderr,  obtained
       from  the explain_fseek(3) function, and	then the process terminates by
       calling exit(EXIT_FAILURE).

       The explain_fseek_on_error function is used to call the fseek(3)	system
       call.  On  failure  an  explanation will	be printed to stderr, obtained
       from the	explain_fseek(3) function, but still returns to	the caller.

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

       offset  The offset, exactly as to be  passed  to	 the  fseek(3)	system
	       call.

       whence  The  whence,  exactly  as  to  be passed	to the fseek(3)	system
	       call.

RETURN VALUE
       The explain_fseek_or_die	function only returns on success, see fseek(3)
       for  more  information. On failure, prints an explanation and exits, it
       does not	return.

       The explain_fseek_on_error function always returns the value return  by
       the wrapped fseek(3) system call.

EXAMPLE
       The  explain_fseek_or_die  function is intended to be used in a fashion
       similar to the following	example:
	      explain_fseek_or_die(fp, offset, whence);

SEE ALSO

	       reposition a stream

       explain_fseek(3)
	       explain fseek(3)	errors
