IVssAdmin::RegisterProvider method (vsadmin.h)

The RegisterProvider method registers a new shadow copy provider.

Syntax

HRESULT RegisterProvider(
  [in] VSS_ID            pProviderId,
  [in] CLSID             ClassId,
  [in] VSS_PWSZ          pwszProviderName,
  [in] VSS_PROVIDER_TYPE eProviderType,
  [in] VSS_PWSZ          pwszProviderVersion,
  [in] VSS_ID            ProviderVersionId
);

Parameters

[in] pProviderId

The VSS_ID that uniquely and persistently identifies the provider. After it is defined, the ProviderId parameter should remain the same, even when the software revision is updated. A ProviderId parameter should be changed only when the functionality changes enough that both providers would be active on the same system. A requester may use the ProviderId parameter to request that a specific provider be used in a shadow copy creation.

[in] ClassId

The CLSID of the provider.

[in] pwszProviderName

The name of the provider.

[in] eProviderType

A VSS_PROVIDER_TYPE enumeration value that specifies the provider type. Note that VSS_PROV_HARDWARE is not a valid provider type on Windows client operating system versions. Hardware providers will run only on Windows server operating system versions.

[in] pwszProviderVersion

The version of the provider.

[in] ProviderVersionId

The VSS_ID that uniquely identifies this version of the provider. The combination of the pProviderId and ProviderVersionId parameters should be unique. The ProviderVersionId parameter can be the same as the ProviderVersionId parameter of another provider.

Return value

This method can return one of these values.

Return code Description
S_OK
The provider was registered successfully.
E_INVALIDARG
One or more of the parameter values is not valid. For example, VSS_PROV_HARDWARE is not a valid provider type on Windows client operating system versions.
E_OUTOFMEMORY
Out of memory or other system resources.
E_ACCESSDENIED
The caller is not an administrator.
VSS_E_PROVIDER_ALREADY_REGISTERED
The provider has already been registered on this computer.
VSS_E_UNEXPECTED
Unexpected error. The error code is logged in the error log file. For more information, see Event and Error Handling Under VSS.

Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  This value is not supported until Windows Server 2008 R2 and Windows 7. E_UNEXPECTED is used instead.

Remarks

If the hardware provider is updated, the setup application should call the UnregisterProvider method to unregister the outdated version, and then call the RegisterProvider method to register the updated provider.

Note  Hardware providers can only be registered on Windows Server operating systems.
