Unregister function fails

[MVS]

Hi sir,

I am automating create machine, booting by attaching vhd or vmdk and taking snapshot. Now i wanna remove the created vm and related backup files as well from the my machine

API I am using :: VirtualBoxSDK-4.2.16-86992 Platform :: Windows7 and Windows 2008 R2 Language :: C++

I have created machine using CreateMachine() function, I can able to create machine, start machine after that following issue troubling me alot

In my VirtualBox.h header file Unregister() and delete() function definitions are as follows.

virtual HRESULT STDMETHODCALLTYPE Unregister( /* [in] */ CleanupMode aCleanupMode, /* [retval][out] */ SAFEARRAY * *aAMedia) = 0;

virtual HRESULT STDMETHODCALLTYPE Delete( /* [in] */ SAFEARRAY * aAMedia, /* [retval][out] */ IProgress aAProgress) = 0;

In my c++ file iam using functions like this

SAFEARRAY * *aAMedia = NULL;

machine->Unregister(CleanupMode_UnregisterOnly , aAMedia); machine->Delete(*aAMedia, &progress);

Here "Unregister()" not returning proper value for "aAMedia" . When iam trying to use the same "aAMedia" in my delete() function as input argument value function fails

Please help me to solve these issue

Regard's MVS
