SafeArray of objects

Question

I want to pass a SafeArray to a function in C++ COM.

I have an object of MetadataListEntity class that I have initialized

IMetadataListEntityPtr metadataListEntity = NULL;
hr = CoCreateInstance(
    __uuidof(MetadataListEntity),
    NULL, 
    CLSCTX_INPROC_SERVER,
    __uuidof(IMetadataListEntityPtr),
    (void**)&metadataListEntity);

metadataListEntity->PutBaseType(0);
metadataListEntity->PutDescription("");
metadataListEntity->PutId("78ba31f9-11ed-4669-9143-c4ac9f11b28b");
metadataListEntity->PutIsChecked(true);
metadataListEntity->PutItemCount(24);
metadataListEntity->PutTitle("AgeMaster");

I want to create an array of MetadataListEntity objects and pass it to a function that accepts a SafeArray.

Ho do I do that ?

Thanks, Gagan
