IPC between 32 bit and 64 bit boost processes

Question

My platform is Visual Studio 2012 and I need to implement IPC between 32 bit and 64 bit processes. I have source code for all binaries but for several reasons one processes should remain 32 bit. I have looked into boost manual and it seems that Boost.Interprocess has everything I need - STL like structures and synchronization object. But couldn't find in docs anything about IPC between 32 bit and 64 bit processes.

Thank you.

I typed `Boost.InterProcess 32 and 64` into google and got this as the first hit: https://svn.boost.org/trac/boost/ticket/5230 and lots of others. Some say it can't be done easily and that you should consider another IPC - like text. — Preet Sangha, May 18 '13 at 10:17

Some IPC methods between 32 and 64 bit processes on Windows don't work, but sockets should work since they aren't dependent on the bitness of the connection.

COM can also be used for IPC between 32-bit and 64-bit processes. If you use the IDL and stick to compatible parameter types it will marshal your parameters and everything. For large blocks of data, pass a handle that can be duplicated and used with MapViewOfFile and you won't have to make a copy of the data. Be careful of thread apartment types.
