Provider::Commit method (provider.h)

[The Provider class is part of the WMI Provider Framework which is now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.]

The Commit method is used to send an instance to WMI. This method is a helper function and should not be overridden.

Syntax

HRESULT Commit(
  CInstance *pInstance,
  bool      bCache
);

Parameters

pInstance

Pointer to the instance to be stored by WMI.

bCache

Indicates whether a cache is implemented. This value must be set to FALSE in the current version of the provider framework.

Return value

Use the SUCCEEDED or FAILED macros on the returned HRESULT to determine if the method was successful.

Remarks

If the client cancels the query, the Commit method returns an error. A provider writer can use this fact to terminate an enumeration.

Also, this method calls CInstance::Release on the pInstance pointer. Because of this, the framework provider must be careful not to call CInstance::Release again. This means that a pInstance smart pointer is incompatible with this method because the smart pointer calls CInstance::Release in its destructor.

This method should only be used when the framework provider does not call CInstance::Release on the pInstance pointer separately and if the pInstance pointer is not, and will never be, a smart pointer.
