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.
-DENTRY_PREFIX=<prefix>
String to be prepended on all the DllGetClassObject etc routines
in dlldata.c. This includes: DllGetClassObject, DllCanUnloadNow
and DllMain, DllRegisterServer, and DllUnregisterServer.
-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.
