METHOD_PROLOGUE
Maintains the proper global state when calling methods of an exported interface.
METHOD_PROLOGUE(theClass, localClass )
Parameters
theClass
Specifies the name of the class whose interface map is being implemented.localClass
Specifies the name of the local class that implements the interface map.
Remarks
Typically, member functions of interfaces implemented by CCmdTarget-derived objects already use this macro to provide automatic initialization of the pThis pointer. For example:
class CMySink : public CCmdTarget
{
public:
CMySink();
~CMySink() {};
protected:
DECLARE_INTERFACE_MAP()
// The following block declares an inner class called 'XSinky'
BEGIN_INTERFACE_PART(Sinky, ISampleSink)
STDMETHOD(SinkFunc)();
END_INTERFACE_PART(Sinky)
};
STDMETHODIMP_(ULONG) CMySink::XSinky::AddRef()
{
METHOD_PROLOGUE(CMySink, Sinky);
return pThis->InternalAddRef();
}
