explain_fseeko_or_die(3)   Library Functions Manual   explain_fseeko_or_die(3)

NAME
       explain_fseeko_or_die  -	seek to	or report file position	and report er-
       rors

SYNOPSIS
       #include	<libexplain/fseeko.h>
       void explain_fseeko_or_die(FILE *fp, off_t offset, int whence);
       int explain_fseeko_on_error(FILE	*fp, off_t offset, int whence);

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

       The explain_fseeko_on_error function is used to call the	fseeko(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_fseeko(3) function, but	still returns to the caller.

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

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

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

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

       The explain_fseeko_on_error function always returns the value return by
       the wrapped fseeko(3) system call.

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

SEE ALSO
       fseeko(3)
	       seek to or report file position

       explain_fseeko(3)
	       explain fseeko(3) errors

       exit(2) terminate the calling process
