A python program opens a new process of the C++ program and is reading the processes stdout. No problem so far.

But is it possible to have multiple streams like this for communication? I can get two if I misuse stderr too, but not more. Easy way to hack this would be using temporary files. Is there something more elegant that does not need a detour to the filesystem?

PS: *nix specific solutions are welcome too
