IWbemClassObject::SpawnInstance method (wbemcli.h)

Use the IWbemClassObject::SpawnInstance method to create a new instance of a class. The current object must be a class definition obtained from Windows Management using IWbemServices::GetObject, IWbemServices::CreateClassEnum, or IWbemServices::CreateClassEnumAsync Then, use this class definition to create new instances.

A call to IWbemServices::PutInstance is required to actually write the instance to Windows Management. If you intend to discard the object before calling IWbemServices::PutInstance, simply make a call to IWbemClassObject::Release.

Note that spawning an instance from an instance is supported but the returned instance will be empty.

Syntax

HRESULT SpawnInstance(
  [in]  long             lFlags,
  [out] IWbemClassObject **ppNewInstance
);

Parameters

[in] lFlags

Reserved. This parameter must be 0.

[out] ppNewInstance

Cannot be NULL. It receives a new instance of the class. The caller must invoke IWbemClassObject::Release when the pointer is no longer required. On error, a new object is not returned and the pointer is left unmodified.
