Parameter	Description
hIiop	Handle to a CORBA object.
sBuffer	Buffer receiving the type code associated with the CORBA object (optional).
nBufferSize	Size of the buffer receiving the type code associate with the CORBA object (optional).
nBufferLen	Variable receiving the actual size of the type code (optional).

Example

dcltrans
  transaction TMain
  const
    HOST   := "192.168.20.21"; // server
    PORT   := 1052;            // port
    KEY    := "...\h00";       // key
    KEYLEN := 4;               // key length
  var
    hIiop     : number;
    sBuffer   : string;
    nTypecode : 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 "GetInfo"
    IiopRequest(hIiop, "GetInfo");

    // check return parameter
    nTypecode := IiopGetTypecode(hIiop, sBuffer);
    ...
    IiopObjectRelease(hIiop);
  end TMain;
