Reading capabilities in c++

Here is sample C++ code which works in accsample deployed with the Open AIM SDK. You can copy and paste the below code and see the capabilities in a debugger.

void OnUserChange( IAccSession* session, IAccUser* oldUser, IAccUser*
newUser, AccUserProp Property, AccResult hr)
{
    CAccVariant cv;
    newUser->get_Property(AccUserProp_Capabilities, &cv);
    SAFEARRAY *psa = V_ARRAY( &cv );
    if(!psa)
    {
        printf(“Why can’t I get capabilities!!”);
    }
    int n = psa->rgsabound[0].cElements;
    for (int i = 0; i < n; i++)
    {
        CAccVariant item;
        long rgIndices[1];
        rgIndices[0] = i;
        SafeArrayGetElement(psa, rgIndices, &item);
    }
}
