-> Using named pipes has been problematic because it returns errors when launching multiple processes aggressively: Error 231 - All Pipes are Busy. This does not happen with anonymous pipes and I think it has some relationship with the guid code. By the way, I think a uuid library is too much to create a unique identifier to be shared with the child a simple atomic count would to the job in my opinion. That would reduce Boost.Process dependencies.
An atomic count might not be sufficient as it would be unique only per process. As I used Boost.Uuid only for convenience though I'll replace it with an atomic count plus a random number to drop the dependency.
The PID of the parent plus an atomic count wouldn't be enough?
-> systembuf::close() should call sync() to push the last charaters into the pipe, othewise, characters are lost if the user does not flush the stream.
Changed (in postream::close()).
I think we must change this in systembuf, because a user might use the streambuf directly and it would be surprised to see that unlike std::filebuf, already written characters are missed. Regards, Ion
