// fsa.cpp : Implementation of DLL Exports.

// Note: Currently, Fsa proxy/stub is compiled into a different DLL.
//      Below is relevant information if it is decided to merge the two DLLs.
// Note: Proxy/Stub Information
//      To merge the proxy/stub code into the object DLL, add the file 
//      dlldatax.c to the project.  Make sure precompiled headers 
//      are turned off for this file, and add _MERGE_PROXYSTUB to the 
//      defines for the project.  
//
//      If you are not running WinNT4.0 or Win95 with DCOM, then you
//      need to remove the following define from dlldatax.c
//      #define _WIN32_WINNT 0x0400
//
//      Further, if you are running MIDL without /Oicf switch, you also 
//      need to remove the following define from dlldatax.c.
//      #define USE_STUBLESS_PROXY
//
//      Modify the custom build rule for ...int.idl by adding the following 
//      files to the Outputs.
//          ...
//          dlldata.c
//      To build a separate proxy/stub DLL, 
//      run nmake -f ...ps.mk in the project directory.
