Distinct - Support - FAQ

This fix addresses the problem where the clnt_broadcast function was not
getting a response from the Distinct portmapper even though the server that the
client is attempting to connect to was registered.

The memory leak that was occuring in the rpc.dll when the portmapper was left
running for a long time has been fixed.


Rpcgen32

1. The problem where the rpcgen32 utility was not producing the right files when
   absolute and relative paths of .x file were used is fixed.
   
2. Two new command line options are added to allow the file to be preprocessed by
   the C-Preprocessor by invoking the C preprocessor. BEFORE you can use this
   option you must add two values to the following registry key:
   
   
   
   
   
   

   HKEY_LOCAL_MACHINE\SOFTWARE/Distinct/Dlls\RPC32 Cpconst D CpDelim "/"

   
   
   
   The first of these sets the compiler definitions option to D and the second sets
   the argument delimeter to /. If your compiler uses different values set these
   here.
   
   
   
   

   By default, preprocessing will not be invoked. To invoke preprocessing follow
   these steps below:

   
   

   To invoke the C-preprocessor use the following syntax when running
   rpcgen32:

   
   
   
   
   

   rpcgen32 -p "compiler arguments" [-D name=value] where: -p invokes the preprocessor "arguments" are the set of arguments required by your compiler -D is optional and is used to specify specific compiler definitions.

   
   
   
   
   When do you need to use C-Preprocessing?
   
   
   Your files will require C-Preprocessing when they contain #if, #else, #ifdef,
   #ifndef, #if defined etc. If the files contain these definitions please use the
   C-Preprocessor option.
   
   
   
   Example
   

   If you are using cl.exe (Microsoft's Visual C++ compiler) the
   argument should be
   -p "cl.exe /EP /nologo" file.x.
   

   The existing command line options can be used in conjunction with -p
   option.

   
   

   If you are using a c-preprocessor other than cl.exe please enter
   the argument list as needed. The argument list should be able to send the
   processed file to the stdout and should only contain information for rcpgen32 to
   do further processing. That is, the output must not contain any banner or text
   issued by the compiler. For Microsoft C++ the /nologo option will inhibit these.
   
   
   
   Warning
   
   
   

   The program creates a temporary file having the name of the .x file but with
   a .i extension. If a file with the same name exists, its contents will be
   overwritten. The file will be created in the directory where the output files
   are generated. This file will be cleaned up before the program exits.

   
   
   

1. When used in the VC++ 6.0 environment the dll caused an access violation
   when the clnt_create() function call was called.
   
2. In VC++6.0 it appears that the select() function call does not honor a specified
   timeout. This was causing an unnecessary increase in the network traffic for
   each client-server call when used under the VC++6.0 environment. A workaround to
   this problem is included in this patch.
   
3. When the server is slow in responding to requests, the dll was not handling
   multiple client calls (clnt_call() function) which were sent from the same
   application in succession.
   
4. Some anomalies reported that were caused by the server receiving several
   megabytes of data have been fixed.
   
5. The xdr_free() routine is now correctly freeing the memory used by pmaplist.
