IPortableDeviceServiceMethods::Invoke method (portabledeviceapi.h)

The Invoke method synchronously invokes a method.

Syntax

HRESULT Invoke(
  [in]      REFGUID               Method,
  [in]      IPortableDeviceValues *pParameters,
  [in, out] IPortableDeviceValues **ppResults
);

Parameters

[in] Method

The method to invoke.

[in] pParameters

A pointer to an IPortableDeviceValues interface that contains the parameters of the invoked method, or NULL to indicate that the method has no parameters.

[in, out] ppResults

The address of a pointer to an IPortableDeviceValues interface that receives the method results, or NULL to ignore the method results.

Return value

If the method succeeds, it returns S_OK. Any other HRESULT value indicates that the call failed.

Remarks

The method invocation is synchronous and will not return until the method has completed. For long-running methods, your application should call the InvokeAsync method instead.
