                                                                                         explain_iconv_or_die(3)

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

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

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

       inbuf   The inbuf, exactly as to be passed to the iconv(3) system call.

       inbytesleft
               The inbytesleft, exactly as to be passed to the iconv(3) system call.

       outbuf  The outbuf, exactly as to be passed to the iconv(3) system call.

       outbytesleft
               The outbytesleft, exactly as to be passed to the iconv(3) system call.

       The explain_iconv_or_die function is intended to be used in a fashion similar to the following example:
              size_t result = explain_iconv_or_die(cd, inbuf, inbytesleft, outbuf,
                  outbytesleft);

       explain_iconv_or_die - perform character set conversion and report errors

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

       The explain_iconv_on_error function always returns the value return by the wrapped iconv(3) system call.
