I have one client and one server talking to each other, and both of them have 2 threads. I want thread 1 in client only talk to thread 1 in server, and thread 2 in client only talk to thread 2 in server. How can I achieve this?
The simple client/server example (http://wiki.tudos.org/L4Re_simple_client_server_example) shows how to connect a single thread in each process (or task in L4 speak). You could extend this example to create two channels in the Lua setup file, pass both channels to the tasks during startup and then let each thread use one of them for communication with its counterpart. Note that does not completely enforce your requirement that each thread can only talk to exactly one other. Capabilities (e.g., for the communication channels) are shared per task and technically each thread could therefore send messages on each channel. If you want strict isolation, you have to separate the threads into separate tasks.
