IWbemConfigureRefresher::AddObjectByPath method (wbemcli.h)

The IWbemConfigureRefresher::AddObjectByPath method adds an object to a refresher by specifying an object path.

Syntax

HRESULT AddObjectByPath(
  [in]  IWbemServices    *pNamespace,
  [in]  LPCWSTR          wszPath,
  [in]  long             lFlags,
  [in]  IWbemContext     *pContext,
  [out] IWbemClassObject **ppRefreshable,
  [out] long             *plId
);

Parameters

[in] pNamespace

An IWbemServices pointer back into Windows Management, which can service any request made by the provider. The provider should call AddRef on this pointer if it is going to call back into Windows Management during its execution.

[in] wszPath

Constant, null-terminated string of 16-bit Unicode characters that contains the object path of the object you add to the refresher.

[in] lFlags

Bitmask of flags that modify the behavior of this method. If this parameter is set to WBEM_FLAG_USE_AMENDED_QUALIFIERS, the returned instance contain localized qualifiers if available.

[in] pContext

Typically NULL; otherwise, a pointer to an IWbemContext object that is required by one or more dynamic class providers. The values in the context object must be specified in the specific provider documentation. For more information about this parameter, see Making Calls to WMI.

[out] ppRefreshable

Pointer to hold the reference to a IWbemClassObject object, which contains the refreshable instance object. The client must call Release on the returned object when it is no longer required.

[out] plId

Pointer to an integer returned by the provider that uniquely identifies the refreshable object.

Return value

This method returns an HRESULT indicating the status of the method call. The following list lists the value contained within an HRESULT.

Remarks

The supplied path must specify a valid object, which is provided by the High-Performance Provider. The returned object must not be touched by the client while a refresh operation is in process. The returned identifier can be used by the Remove function to remove the object.

Note  It is not necessary for the user to explicitly remove added objects. The client must call Release on the returned object when it is no longer required.
