Flags (2 bytes): An unsigned integer that contains information for some records on how the operation is to be performed and on the structure of the record.

Size (4 bytes): An unsigned integer that defines the 32-bit-aligned size of the entire record in bytes, including the 12-byte record header and the record-specific data.

DataSize (4 bytes): An unsigned integer that defines the 32-bit-aligned number of bytes of data in the RecordData field that follows. This number does not include the 12-byte record header.

RecordData (variable): An optional, variable-length array of bytes that, if present, defines the data specific to individual records. For specifications of the additional information, if any, which is contained within this field, see individual record definitions.
