IVdsProviderPrivate::OnLoad method (vdshwprv.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Prompts the provider to initialize itself, and passes a callback object that the provider uses to get necessary interfaces.
Syntax
HRESULT OnLoad(
[in] LPWSTR pwszMachineName,
[in] IUnknown *pCallbackObject
);
Parameters
[in] pwszMachineName
This parameter is reserved.
[in] pCallbackObject
Pointer to a callback object.
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 |
---|---|
|
The provider is initialized. |
|
The provider failed to initialize. |
Remarks
VDS calls this method immediately after calling the CoCreateInstance method on a provider.
Implementers must implement this method. Invoke the IUnknown::QueryInterface method to query for the IVdsAdviseSink interface.
