Syntax

IiopGetDataByTypecode( in  hIiop       : number,
                       in  sTypeCode   : string,
                       in  nCodeLength : number optional,
                       out sBuffer     : string optional,
                       in  nSize       : number optional,
                       out nReceived   : number optional ): boolean;

Return value

true if successful
false otherwise

Parameter	Description
hIiop	Handle to a CORBA object.
sTypeCode	Type code that specifies which data is to be retrieved from the CORBA object.
nCodeLength	Length of the type code that specifies which data is to be retrieved from the CORBA object (optional).
sBuffer	Buffer that will receive the data from the CORBA object (optional).
nSize	Size of the buffer that will receive the data from the CORBA object (optional).
nReceived	Variable that will receive the number of bytes that were actually retrieved from the CORBA object (optional).

Example

dcltrans  transaction
 TGetChar
  const
    HOST   := "192.168.20.21"; // server
    PORT   := 1052;            // port
    KEY    := "...\h00";       // key
    KEYLEN := 4;               // key length
  var
    hIiop              : number; // Handle to CORBA object
    sBuffer, sTypecode : string;    nTypecode, nLength : number;
  begin    IiopSetMaxGiopVersion("1.0");
    IiopSetByteOrder(IIOP_BIG_ENDIAN);
     
    // retrieve handle to server
    IiopObjectCreate(hIiop, "IDL:DemoObject:1.0", "1.2", HOST, PORT, KEY, KEYLEN);

    // call request "GetLong"
    IiopRequest(hIiop, "GetLong");
    SetLong(sTypecode, 1, IIOP_TK_LONG);
    IiopGetDataByTypecode(hIiop, sTypecode, STRING_COMPLETE, sBuffer);

    Print("GetLong returned: " + string(GetLong(sBuffer, 1)));
    IiopObjectRelease(hIiop);
  end TGetChar;
