Parameter Adaption

Parameter adaptions are used in adapter functions. A parameter adaption takes care of the necessary conversion of one parameter between the Xbase++ world and the called dll function. Depending on the parameter type and the passing direction (in,out,reference) a parameter adaption connects the Xbase++ parameter with the actual parameter passed on to and returned by the called function. Parameter adaptions are used in adapter functions and COM interface adapter methods. Parameter adaptions are based on parameter adaption specs.
