Re: Working on ATL, more real world test case needed

[Vincent Povirk]

ATL_PROPMAP_ENTRY is the same from atl71 through atl90. In atl100 and
atl110 it looks like this:

struct ATL_PROPMAP_ENTRY
{
    LPCOLESTR szDesc;
    const CLSID* pclsidPropPage;
    const IID* piidDispatch;
    void *rgclsidAllowed;
    DWORD cclsidAllowed;
    DISPID dispid;
    DWORD dwOffsetData;
    DWORD dwSizeData;
    VARTYPE vt;
};

While the structure itself is undocumented, there are documented
macros that create it:

For the callback macros, the callback function is stored in
rgclsidAllowed, and cclsidAllowed is 0. The only public mention of the
callback signature I could find is in this article:
