IWbemServices::CreateInstanceEnumAsync

[This is preliminary documentation and subject to change.]

The IWbemServices::CreateInstanceEnumAsync method performs the same task as IWbemServices::CreateInstanceEnum except that the call returns immediately, and the instances are asynchronously provided to the specified response handler.

HRESULT IWbemServices::CreateInstanceEnumAsync(
  [in] BSTR bstrClass, 
  [in] LONG lFlags, 
  [in] IWbemContext *pCtx, 
  [in] CALLBACK *pResponseHandler 
);
 

Parameters

bstrClass

A valid BSTR containing the name of the class for which instances are desired. This parameter cannot be NULL.

lFlags

When set to zero, WBEM_FLAG_DEEP forces recursive enumeration into all subclasses derived from the specified class. Instances of Class as well as those of its derived classes are returned. WBEM_FLAG_SHALLOW forces the enumeration to include only instances of the specified class.

pCtx

Typically NULL. Otherwise, this is a pointer to an IWbemContext object required by the dynamic class provider that is producing the class instances. The values in the context object must be specified in the documentation for the provider in question.

pResponseHandler

Points to the caller's implementation of IWbemObjectSink. This handler receives the objects as they become available. For a detailed explanation of this parameter, see Asynchronous Methods. CIMOM only calls AddRef on the pointer in cases where WBEM_NO_ERROR is returned. In cases where an error code is returned, the reference count is the same as on entry.

Return Values

On failure, you can obtain additional information from the COM function GetErrorInfo.
