hid_t loc_idIN: Identifier of the file or group to read the table within
const char *table_nameIN: The name of the dataset to read
int nfieldsIN: The number of fields to read (This parameter is also the size of the field_index array.)
const int * field_indexIN: The indexes of the fields to read
hsize_t  startIN: The start record to read from
hsize_t nrecordsIN: The number of records to read
hsize_t type_sizeIN: The size in bytes of the structure associated with the table. (This value is obtained with sizeof.)
const size_t *field_offsetIN: An array containing the offsets of the fields
const size_t *dst_sizesIN: An array containing the size in bytes of the fields
void *dataOUT: Buffer with data


H5TB_READ_FIELDS_INDEX reads the fields identified by  field_index from a dataset named table_name attached to the object specified by the identifier loc_id


Returns a non-negative value if successful; otherwise returns a negative value.
