Retrieves a double value return parameter from a CORBA object. This function can be used to get the return parameters of an operation.

Include file

IIOP.bdh

Syntax

IiopGetDouble( in  hIiop  : number,
               out fValue : float optional ): float;

Return value

Double value associated with the CORBA object

Parameter	Description
hIiop	Handle to a CORBA object
fValue	Variable receiving the double value associated with the CORBA object (optional)

Example

dcltrans
  transaction TGetDouble
  const
    HOST   := "192.168.20.21"; // server
    PORT   := 1052; // port
    KEY    := "...\h00"; // key
    KEYLEN := 4; // key length
  var
    hIiop : number; // Handle to CORBA object
    fSqrt : float;
  begin
    IiopSetMaxGiopVersion("1.2");
    IiopSetByteOrder(IIOP_BIG_ENDIAN);

    // retrieve handle to server
    IiopObjectCreate(hIiop, "IDL:DemoObject:1.0", "1.2",
                     HOST, PORT, KEY, KEYLEN);

    // call request "SquareRoot" with double value parameter
    IiopSetDouble(hIiop, 685083.117);
    IiopRequest(hIiop, "SquareRoot");

    // retrieve double value return parameter
    fSqrt := IiopGetDouble(hIiop);

    write("square root = "); write(fSqrt); writeln;
    IiopObjectRelease(hIiop);
  end TGetDouble;

Output

square root = 827.697479
