                                                                                   explain_iconv_close_or_die(3)

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

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

       cd      The cd, exactly as to be passed to the iconv_close(3) system call.

       The explain_iconv_close_or_die function is intended to be used in a  fashion  similar  to  the  following
       example:
              explain_iconv_close_or_die(cd);

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

       The  explain_iconv_close_on_error  function always returns the value return by the wrapped iconv_close(3)
       system call.
