IVdsService::Advise method (vds.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Registers the caller's IVdsAdviseSink interface with VDS so that the caller receives notifications from the VDS service.

Syntax

HRESULT Advise(
  [in]  IVdsAdviseSink *pSink,
  [out] DWORD          *pdwCookie
);

Parameters

[in] pSink

A pointer to the IVdsAdviseSink interface.

[out] pdwCookie

A pointer to a cookie that can later be used to unregister the interface.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code/value	Description
S_OK	The registration completed successfully.
VDS_E_INITIALIZED_FAILED 0x80042401L	VDS failed to initialize. If an application calls this method before the service finishes initializing, the method is blocked until the initialization completes. If the initialization fails, this error is returned.

Remarks

To receive notifications from the VDS service, your application must implement the IVdsAdviseSink interface and use the Advise method to register the interface.

To stop receiving notifications from the VDS service, use the IVdsService::Unadvise method to unregister the IVdsAdviseSink interface.

To receive notifications from underlying software and hardware providers, VDS passes a notification callback function to each provider as a parameter of the IVdsProviderPrivate::OnLoad method.
