The IWbemServices::CreateInstanceEnum method creates an enumerator that returns the instances of a specified class according to user-specified selection criteria. This method supports simple WQL queries; more complex queries can be processed using the IWbemServices::ExecQuery method.
Valid BSTR containing the name of the class for which instances are desired. This parameter cannot be NULL.
The following flags affect the behavior of this method. The suggested value for this parameter is WBEM_FLAG_RETURN_IMMEDIATELY and WBEM_FLAG_FORWARD_ONLY for best performance.
If this flag is set, WMI retrieves the amended qualifiers stored in the localized namespace of the current connection's locale. If not set, only the qualifiers stored in the immediate namespace are retrieved.
This flag forces the enumeration to include this and all subclasses in the hierarchy.
This flag forces the enumeration to include only pure instances of this class, excluding all instances of subclasses which supply properties not found in this class.
This flag causes this to be a semisynchronous call. For more information, see Calling a Method.
This flag causes a forward-only enumerator to be returned. Forward-only enumerators are generally much faster and use less memory than conventional enumerators but do not allow calls to Clone or Reset.
This flag causes Windows Management to retain pointers to objects of the enumeration until the client releases the enumerator. Because object pointers are not released immediately, this method may fail with a hResult of WBEM_E_OUT_OF_MEMORY if the client attempts to enumerate a large number of objects. This flag is implied by default if you set the lFlags parameter to 0 (zero).
This flag causes direct access to the provider for the class specified without any regard to its parent class or subclasses.
Typically NULL. Otherwise, this is a pointer to an IWbemContext object that may be used by the provider that is providing the requested instances. The values in the context object must be specified in the documentation for the provider in question. For more information about this parameter, see Making Calls to WMI.
Receives the pointer to the enumerator, which has a positive reference count. The caller must call IUnknown::Release on the pointer after it is no longer required.
This method returns an HRESULT indicating the status of the method call. The following list lists the value contained within an HRESULT.
On failure, you can obtain any available information from the COM function GetErrorInfo.
COM-specific error codes also may be returned if network problems cause you to lose the remote connection to Windows Management.
It is not an error for the returned enumerator to have zero elements.
