 VOID
 NdrProxyForwardingFunction<nnn>(...)

 Routine Description:

    This function forwards a call to the proxy for the base interface.

 Arguments:

    This [a0] - Points to an interface proxy.

 Return Value:

    None.

// here is what a forwarder looks like
// we must:
//      change the "this" pointer in [esp+4] to point to the delegated object
//      fetch the correct entry from the vtable
//      call the function

#define SUBCLASS_OFFSET     32
#define VTABLE_ENTRY(n)     n*8

/*
    this is a macro for delegation methods. It first retrives BaseProxyBuffer
    from the proxy vtbl, then deference to get the base vtbl.  From the offset
    in vtbl, we get the pair of real .ObjectStublessClient##method_number
    and gp. bp & b6 is loaded up accordingly and the code is branched into
    ObjectStublessClient##method_number
