How do I get a list of assets (AssetIDList) from a library?

Question

I've been looking through the SDK documentation and samples for a way to delete all the assets in a libary. I've got a pointer to the library (ILibrary *) and the command ILibraryCmdUtils::ProcessLibraryDeleteItemsCmd() which takes an asset list and the library pointer.
The part I can't work out is how to get the asset list (AssetIDList) from the library to pass to the above command.
Some ideas are:
ILibraryScrapData - but I don't know how I can get a pointer to this and if I could is it simply a case of calling SetLibrary() followed by GetAssetList()?
AssetLibUtils.h - not documented, so no idea how to use the classes or functions.
I expected this to be a trivial task, but so far finding solutions to this and other seemingly simple tasks is proving very frustrating! Could someone point me in the right direction?
Thanks in advance.

Solved it at last! It turns out that the 2nd idea is the way to go.
There is some sample code in source\open\components\buttonui\utils\FormFieldUIUtils.cpp FormFieldUIUtils::AdjustStylePresetMenu() that shows how you can get an ILibraryAsset pointer for each asset in the library. So I just use AssetIDList::push_back( ptrAsset->GetID() ) to build up an AssetIDList that can be passed to ILibraryCmdUtils::ProcessLibraryDeleteItemsCmd().
Why Adobe can't just have a GetAssetList() function for ILibrary I've no idea! I'm also troubled by the fact that as AssetLibUtils.h is undocumented, Adobe might decide to remove it in future SDK builds.
void MyLibraryClass::DeleteAssets()
    class LibraryAssets : public AssetEnumerator
    public:
        AssetIDList m_AssetList;
        LibraryAssets() {}
        virtual bool operator()(ILibraryAsset *ptrAsset)
            m_AssetList.push_back( ptrAsset->GetID() );
            return true;
    LibraryAssets LibraryAssetsToDelete;
    AssetLibUtils::EnumerateAssets( m_ptrLibrary, &LibraryAssetsToDelete );
    if (LibraryAssetsToDelete.m_AssetList.size() > 0)
        // Create and process command to delete items from library...
