Sometime communication between two processes requires to accomplish a task. Symbian OS provides client-server architecture for IPC.
Read the following sections for more theoretical explanation.
Lets take an example of communication between two applications, ClientApplication and ServerApplication.
ClientApplication
- Create a class and derive it from RSessionBase.
- Create Session with server using RSessionBase::CreateSession(). //for creating session server must be running on there side.
- Send messege through RSessionBase::SendReceive(). // first parameter is message id, second is message.
ServerApplication
- Create a class and derive it from CServer2 and CSession2.
- Start a server using CSever2::StartL().
- Create a session with CServer2::NewSessionL().
- Receive message in CSession2::ServiceL().
Note: For second edition use CServer,CSharableSession instead of CSever2 and CSession2.
