- INTEROP
-
-
- The INTEROP program demonstrates portability between OSF DCE RPC and
- Microsoft RPC.
-
- SUMMARY
- =======
-
- The INTEROP program sends simple messages (strings) from the client to the
- server. The most important part of INTEROP is the header file dceport.h.
- This header file maps OSF DCE RPC APIs and data structures to the
- Microsoft RPC equivalents.
-
- FILES
- =====
-
- The directory samples\rpc\interop contains the following files for building
- the distributed application INTEROP:
-
- File Description
-
- README.TXT Readme file for the INTEROP sample
- MSG.IDL Interface definition language file
- MSG.ACF Attribute configuration file
- DCEPORT.H Maps OSF APIs and structures to Microsoft RPC equivalents
- CLIENT.C Client main program
- SERVER.C Server main program
- MIDLUSER.C Memory management routines for Microsoft RPC
- MANAGER.C Client-side utility routines
- MAKEFILE Nmake file to build for Windows NT or Windows 95
- MAKEFILE.DOS Nmake file to build for MS-DOS
- MAKEFILE.DOS Makefile to build for DCE platform
-
- ------------------------------------
- Building on 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
-
- --------------------------
- Building on MS-DOS Systems
- --------------------------
-
- 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 msg.h
-
- Step Two: Compile the C sources (stub and application):
-
- nmake -f makefile.dos
-
- Building on DCE Systems
- -----------------------
-
- You need to copy the following files to the DCE machine:
-
- client.c
- server.c
- manager.c
- msg.idl
- msg.acf
- makefile.dce
-
- make -f makefile.dce cleanall all
-
- Note: You will probably need to change the CFLAGS and LIBS
- variables in makefile.dce to match your platform.
-
- Using the program:
- ------------------
-
- The basic example:
-
- Run:
- server
- on the server machine.
-
- Run:
- client -n <server name> -s "Hi, I'm a client"
- on the client machine to send the message.
-
- Run:
- client -n <server name> -s "Okay, stop this example" -x
- on the client machine to send the message and cause the server to stop.
-
- You can use fixed endpoints by adding the -e switch:
-
- server -e 3452
- client -e 3452 -n <server name> -s "Hi, I'm a client"
- client -e 3452 -n <server name> -s "Okay, stop this example" -x
-
- You can run the demo over a different protocol by adding a -t switch
- to both the client and server:
-
- server -t ncacn_np
- client -t ncacn_np -n <server name> -s "Hi, I'm a client"
- client -t ncacn_np -n <server name> -s "Okay, stop this example" -x
-
- Options:
- --------
-
- The -h switch displays a usage message.
-
- The -s <message> switch is used to change with message sent from the client
- to the server. Without it the message "Hello World" is sent.
-
- The -n <server_name> switch is used for specifying a server machine.
- Without it the server is assumed to run on the same machine.
-
- The -e <endpoint> switch is used to specify a fixed endpoint to be used.
- Without it a dynamic endpoint will be used and registered with the
- endpoint mapper.
-
- The -t <protseq> switch is used to specify which protocol to use. Without
- it the protocol sequence "ncacn_ip_tcp" will be used.
-
- ----------------------
- RUNNING ON WINDOWS 95:
- ----------------------
-
- If you wish to run the server on Windows 95, you will need to use
- the LRPC protocol.
-
- To start the server, enter:
-
- server -t ncalrpc
-
- To start the client (from the same machine), enter:
-
- client -t ncalrpc
-
