CALLBACK 
 
 
The CALLBACK program demonstrates the use of the callback attribute to  
allow a server application to execute code on a client application. The  
distributed program generates a Fibonacci number with a static callback. 
 
The directory samples\rpc\callback contains the following files for 
building the sample distributed application CALLBACK:

CALL.IDL        Interface definition language file 
CALL.ACF        Application configuration file 
CALLC.C         Client main program 
CALLS.C         Server main program 
CALLP.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 callc.exe (client) and calls.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 callc.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 hello.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: 
 
  calls 
 
On the client, enter: 
 
  net start workstation 
  callc 
 
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: 
 
  callc -? 
 
For a listing of switches available from the server program, enter: 
 
  calls -?
