 Module Name:

    FailObsoleteShellAPIs.cpp

 Abstract:

    Some applications call private shell32 APIs that have been removed since win2k.
    To make matters worse, these old ordinals are now used by other shell APIs. To
    prevent resulting crashes, we now hand out stubbed out functions that fail when
    you call GetProcAddress with these obsolete ordinals.

 Notes:

    This is a general purpose shim.
