gd_encoding — report the binary encoding of data in a Dirfile

       The gd_encoding() function queries a dirfile(5) database specified by dirfile and returns the data encod‐
       ing for the fragment indexed by fragment_index.  The data encoding of a fragment indicate the encoding of
       data files associated with RAW fields defined in the specified fragment.  The encoding of a fragment con‐
       taining no RAW fields is ignored.

       The get_encoding() function appeared in GetData-0.5.0.

       In GetData-0.7.0, this function was renamed to gd_encoding().

       gd_encoding — report the binary encoding of data in a Dirfile

       Upon  successful  completion,  gd_encoding() returns the binary encoding of the specified fragment, which
       will one of the following symbols:

              GD_UNENCODED, GD_BZIP2_ENCODED, GD_FLAC_ENCODED, GD_GZIP_ENCODED, GD_LZMA_ENCODED, GD_SIE_ENCODED,
              GD_SLIM_ENCODED, GD_TEXT_ENCODED, GD_ZZIP_ENCODED, GD_ZZSLIM_ENCODED, GD_ENC_UNSUPPORTED.

       If the encoding scheme specified in the dirfile metadata is unknown to GetData,  GD_ENC_UNSUPPORTED  will
       be returned.  See gd_open(3) and dirfile-encoding(5) for the meanings of the other symbols and details on
       the supported encoding schemes.

       On  error, this function returns zero and stores a negative-valued error code in the DIRFILE object which
       may be retrieved by a subsequent call to gd_error(3).  Possible error codes are:

       GD_E_BAD_DIRFILE
               The supplied dirfile was invalid.

       GD_E_BAD_INDEX
               The supplied index was out of range.

       A descriptive error string for the error may be obtained by calling gd_error_string(3).
