[chromium-dev] Re: Chromium IPC layer in 64-bit MacOS
Someone runs Chromium 64bits in MAC OS X? I want to try in Snow Leopard!

There is almost no OS X specific code in /ipc and it works on 64-bit Linux. There is a very high probability that it'll work just fine on 64-bit OS X.

[chromium-dev] Re: Chromium IPC layer in 64-bit MacOS
Hi Mark, We haven't specifically tested the ipc layer as a method to communicate between 64 32-bit processes on OS X. At it's core the IPC layer just consists of a pipe to which we read write binary data, therefore if the binary representation of the data types that you want to push over the ipc channel are compatible between both processes, you *should* be fine. I don't know what your use case is, but one concern I would have is passing file descriptors back and forth, while this should work it's untested.
