decodeReply function

OncRpcReply decodeReply(List<int> body)

Decode an ONC RPC reply message body (without the record marker).

Implementation

OncRpcReply decodeReply(List<int> body) {
  final r = XdrReader(body);
  final xid = r.readUint32();
  final msgType = r.readUint32();
  if (msgType != 1) {
    throw OncRpcError('expected REPLY (msg_type=1), got $msgType');
  }
  final replyStat = r.readUint32();
  if (replyStat == ReplyStatus.msgDenied) {
    return OncRpcReply(
      xid: xid, acceptStat: -1, denied: true,
      resultBytes: Uint8List(0),
    );
  }
  // msg_accepted: read verf + accept_stat.
  r.readUint32(); // verf flavor
  r.readOpaque(); // verf body (always empty for AUTH_NONE)
  final acceptStat = r.readUint32();
  final result = body.sublist(r.offset);
  return OncRpcReply(
    xid: xid, acceptStat: acceptStat, denied: false,
    resultBytes: Uint8List.fromList(result),
  );
}
