Creates a property data object, that is, an IPropData object.
[in] Pointer to an interface identifier (IID) for the property data object. The valid interface identifier is IID_IMAPIPropData. Passing NULL in the lpInterface parameter also causes the property data object returned in the lppPropData parameter to be cast to the standard interface for a property data object.
The lpAllocateBuffer, lpAllocateMore, and lpFreeBuffer input parameters point to the MAPIAllocateBuffer, MAPIAllocateMore, and MAPIFreeBuffer functions, respectively. A client application calling CreateIProp passes in pointers to the MAPI functions just named; a service provider passes the pointers to these functions it received in its initialization call or retrieved with a call to the IMAPISupport::GetMemAllocRoutines method.
