Module Name:

    OLEWRAP.CPP

Abstract:

    Wrapper classes for COM data type functions.  

    If a COM data function is required to allocate memory and fails to do 
    so, then a CX_MemoryException exception is thrown.  All COM data type 
    functions are wrapped, regardless if they allocate memory, for the sake  
    of completeness.

History:

    a-dcrews    19-Mar-99   Created.
