How does Chrome share data between its processes?

I also would like to apply the same technique to my app, but I don't know how Chrome shares data(of the current tab) to the main process(user interface). How would that be possible? How they do it?

The Apache webserver uses a Scoreboard file to coordinate between the master and slave processes.

It initially tries to use a shared memory segment (such as from shm_open(2)), followed by mmap(2) of a plain file. Either approach works well. I imagine Apache forces all accesses to its scoreboard via semaphores (sem_open(2)), but if the updates are atomic single-writes, it may not need to.

According to this design document, Chrome uses named pipes as its IPC transport mechanism on Windows platforms, and socket pairs under Linux and OS X.
