                                                                                    explain_iconv_open_or_die(3)

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

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

       tocode  The tocode, exactly as to be passed to the iconv_open(3) system call.

       fromcode
               The fromcode, exactly as to be passed to the iconv_open(3) system call.

       The  explain_iconv_open_or_die  function  is  intended  to  be used in a fashion similar to the following
       example:
              iconv_t result = explain_iconv_open_or_die(tocode, fromcode);

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

       The explain_iconv_open_on_error function always returns the value return  by  the  wrapped  iconv_open(3)
       system call.

       explain_iconv_open(3)
