define, initialize and use types in js-ctypes

Question

SCardTransmit function is defined in https://msdn.microsoft.com/en-us/library/windows/desktop/aa379804%28v=vs.85%29.aspx

I want to declare and use this function, I have problems with the definition of some arguments in js-ctypes (especially in type casting):

1. LPCSCARD_IO_REQUEST: A pointer to the protocol header structure
2. LPCBYTE: A pointer to the actual data to be written to the card
3. LPBYTE: Pointer to a 32-byte buffer that receives the ATR string from the currently inserted card, if available. (this arg is in the status function)

How Can define, initialize and use them?

Here my code:

//-----------------define types----------------------    
Cu.import('resource://gre/modules/ctypes.jsm');
var TYPES = {
ABI: is64bit ? ctypes.default_abi : ctypes.winapi_abi,
DWORD: ctypes.uint32_t,
LONG: ctypes.long,
BYTE: ctypes.unsigned_char //ctypes.uint8_t
};
TYPES.LPDWORD = TYPES.DWORD.ptr;
TYPES.SCARDCONTEXT = TYPES.ULONG_PTR;
TYPES.SCARDHANDLE = TYPES.ULONG_PTR;
TYPES.LPBYTE = TYPES.BYTE.ptr;
var CONST = { 
SCARD_PROTOCOL_T0: 0x00000000,
SCARD_PROTOCOL_T1: 0x00000001
}

const SCARD_IO_REQUEST = new ctypes.StructType("myStruct" ,
                   [{"dwProtocol": TYPES.DWORD},
                    {"cbPciLength": TYPES.DWORD}]);

//------------------declaration-------------------------
var SCardTransmit = cardLib.declare('SCardTransmit', TYPES.ABI, TYPES.LONG, TYPES.SCARDHANDLE, SCARD_IO_REQUEST.ptr, TYPES.LPBYTE, TYPES.DWORD, SCARD_IO_REQUEST.ptr, TYPES.LPBYTE, TYPES.LPDWORD);
//------------------initializing---------------------
var _SCARD_IO_REQUEST = new SCARD_IO_REQUEST;
    _SCARD_IO_REQUEST.dwProtocol = CONST.SCARD_PROTOCOL_T0|CONST.SCARD_PROTOCOL_T1;
    _SCARD_IO_REQUEST.cbPciLength = _SCARD_IO_REQUEST.dwProtocol.toString().length;
var command = ctypes.char.array(42)("00a4040010a0000000183003010000000000000000");
var commandLength = command.toString().length;
var response = TYPES.LPBYTE;
var responseLength = TYPES.LPDWORD;      
//----------------using-------------------------
var rez_SCT = SCardTransmit(cardHandle, _SCARD_IO_REQUEST, command, commandLength, null, response, responseLength.address());
if(rez_SCT.toString() != CONST.SCARD_S_SUCCESS.toString())
    {
      console.error('cannot begin transaction, error code was: ' + rez_SCT + ' in other terms it is: 0x' + rez_SCT.toString(16) + ' you can look up this error value here: https://msdn.microsoft.com/en-us/library/windows/desktop/aa374738%28v=vs.85%29.aspx#smart_card_return_values');
      throw new Error('failed to begin transactio!');
     }
