NAME
       explain_telldir_or_die  -  current location in directory	and report er-
       rors

SYNOPSIS
       #include	<libexplain/telldir.h>
       off_t explain_telldir_or_die(DIR	*dir);
       off_t explain_telldir_on_error(DIR *dir);

DESCRIPTION
       The explain_telldir_or_die function is used to call the telldir(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_telldir(3) function, and then the  process  terminates
       by calling exit(EXIT_FAILURE).

       The  explain_telldir_on_error  function	is used	to call	the telldir(3)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained  from  the explain_telldir(3) function, but still	returns	to the
       caller.

       dir     The dir,	exactly	as to be passed	to the telldir(3) system call.

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

       The explain_telldir_on_error function always returns the	 value	return
       by the wrapped telldir(3) system	call.

EXAMPLE
       The explain_telldir_or_die function is intended to be used in a fashion
       similar to the following	example:
	      off_t result = explain_telldir_or_die(dir);
