DUNION


The DUNION program illustrates discriminated unions.

FILES
=====

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 -?
