CLUUID
The CLUUID program demonstrates how to supply multiple implementations of
the remote procedure specified in the interface. It also demonstrates
how the client selects among the implementations by providing a client
object uuid.
SUMMARY
=======
The server calls RpcObjectSetType to associate a client object uuid with
the object uuid in the Object Registry Table. The server initializes a
manager entry point vector (manager epv) and then calls RpcRegisterIf to
associate the interface uuid and the object uuid with the manager epv in
the Interface Registry Table.
When the client makes a remote procedure call, the client object uuid is
mapped to the object uuid in the Object Registry Table. The resulting
object uuid and the interface uuid are mapped to a manager entry point
vector in the Interface Registry Table.
By default, in this example, the server registers two implementations of
the "hello, world" function HelloProc and HelloProc2. The HelloProc2
implementation is associated with the object uuid
"11111111-1111-1111-1111-111111111111". When the client makes a procedure
call with a null uuid, the client's request is mapped to the original
HelloProc. When the client makes a procedure call with the client object
uuid "11111111-1111-1111-1111-11111111111", the client's request is mapped
to HelloProc2 (which prints the string in reverse).
FILES
=====
The directory samples\rpc\cluuid contains the following files for
building the sample distributed application CLUUID:
File Description
README.TXT Readme file for the cluuid sample
CLUUID.IDL Interface definition language file
CLUUID.ACF Attribute configuration file
CLUUIDC.C Client main program
CLUUIDS.C Server main program
CLUUIDP.C Remote procedures
MAKEFILE Nmake file to build for Windows
-------------------------------------------
BUILDING CLIENT AND SERVER APPLICATIONS
-------------------------------------------
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 cluuidc.exe(client) and
cluuids.exe (server).
------------------------------------------
RUNNING THE CLIENT AND SERVER APPLICATIONS
------------------------------------------
On the server, enter:
cluuids
On the client, enter:
net start workstation
cluuidc
To call the second implementation of the function,
on the client, enter:
cluuidc -u "11111111-1111-1111-1111-111111111111"
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:
cluuidc -?
For a listing of switches available from the server program, enter:
cluuids -?
