Subject: IPC implementation in Linux

Hello,

I have a question concerning the implementation of the IPC mechanisms in Linux. Unfortunately I didn't find any further information in the web.

1. There is the Shared memory mechanism: So far as I know it maps some processes address space to the address space
of another process. Through this address space the two processes can exchange information. This way of IPC is quite replicable 
for me.

2. But how are the IPC mechanisms like message queues or pipes/FIFOs realized? Are they workng with a shared address space too?

Best regards
