The directory samples\rpc\handles\data\dunion contains the following files 
to build the distributed application DUNION: 
 
File          Description 
 
README.TXT    Readme file for the DUNION sample 
DUNION.IDL    Interface definition language file 
DUNION.ACF    Attribute configuration file 
DUNIONC.C     Client main program 
DUNIONS.C     Server main program 
DUNIONP.C     Remote procedures 
MAKEFILE      Nmake file to build for Windows NT or Windows 95 
MAKEFILE.DOS  Nmake file to build for MS-DOS 
 
------------------------------------------- 
BUILDING CLIENT AND SERVER APPLICATIONS FOR 
MICROSOFT WINDOWS NT OR WINDOWS 95 
------------------------------------------- 
 
The following environment variables should be already set for you: 
 
  set CPU=i386 
  set INCLUDE=%SDKROOT%\h 
  set LIB=%SDKROOT%\lib 
  set PATH=%SDKROOT%\system32;%SDKROOT%\bin 
 
where %SDKROOT% is the root directory for the 32-bit Windows SDK. 
 
For mips, set CPU=mips 
For alpha, set CPU=alpha 
 
Build the sample distributed application: 
  
 nmake cleanall 
 nmake 
 
This builds the executable programs dunionc.exe 
(client) and dunions.exe (server). 
 
------------------------------------------ 
BUILDING THE CLIENT APPLICATION FOR MS-DOS 
------------------------------------------ 
 
After installing the Microsoft Visual C/C++ version 1.50 development 
environment and the 16-bit RPC SDK on a Windows NT or Windows 95 
computer, you can build the sample client application from Windows NT 
or Windows 95: 
 
  nmake -f makefile.dos cleanall 
  nmake -f makefile.dos 
 
This builds the client application dunionc.exe. 
 
You may also execute the Microsoft Visual C/C++ compiler under MS-DOS. 
This requires a two-step build process. 
 
  Step One: Compile the .IDL files under Windows NT or Windows 95: 
 
     nmake -a -f makefile.dos dunion.h 
 
  Step Two: Compile the C sources (stub and application) under MS-DOS: 
 
     nmake -f makefile.dos 
 
------------------------------------------ 
RUNNING THE CLIENT AND SERVER APPLICATIONS 
------------------------------------------ 
 
On the server, enter: 
 
  dunions 
 
On the client, enter: 
 
  net start workstation 
  dunionc 
 
Note:  The client and server applications can run on the same Microsoft  
Windows NT computer when you use different screen groups. 
 
Several command line switches are available to change settings for this  
program. For a listing of the switches available from the client program,  
enter: 
 
  dunionc -? 
 
For a listing of switches available from the server program, enter: 
 
  dunions -?
