Accessing client address space from server

Hi All,

I have a question regaring Client -Server IPC. My Server and Client are 2 different threads running in 2 different Process. I am sending poinet to an HBufC from the Server using TIpcArgs and in the server side.

I am extracting that pointer using from RMessage::ReadL  and trying to write some data on to that location (which is in client's address space ). But its getting PANICed with KERN-EXEC 0.

Now, my question is, is it possible to modify client's address space (which is in different process) from server? If so, how to do that? I am using Symbian 9.1 with PLATSEC.

Thanks in advance for the help.
