/*++

Copyright (c) 1992-1996 Microsoft Corporation

Module Name:

    rpcproxy.h

Abstract:

    Definitions for rpc proxy  stubs.

Compiler switches:

    -DREGISTER_PROXY_DLL
        Generates DllMain, DllRegisterServer, and DllUnregisterServer functions
        for automatically registering a proxy DLL.

    -DPROXY_CLSID=clsid
        Specifies a class ID to be used by the proxy DLL.

    -DPROXY_CLSID_IS={0x6f11fe5c,0x2fc5,0x101b,{0x9e,0x45,0x00,0x00,0x0b,0x65,0xc7,0xef}}
        Specifies the value of the class ID to be used by the proxy DLL.

    -DNT35_STRICT
        Specifies that the target platform is Windows NT 3.5. This switch disables
        the new functions added after the Windows NT 3.5 release.
