Interprocess support for Pipe
Hi, Does boost interprocess support "pipe" like operations. That is if process A writes something and when process B reads it, the memory content should be reset. If I use shared memory, it complicates things. Thanks, Lloyd

No, it does not support it. Maybe the message queue could help. Ion

There is a create_pipe() function in what's usually called Boost.Process (not an official Boost library - work in progress for roughly 10 years ;) - see http://www.highscore.de/boost/process0.5/boost/process/create_pipe_id341354..... However you can't use the pipe for asynchronous I/O on Windows. Someone else worked on a named pipe for Boost two years ago (see http://thread.gmane.org/gmane.comp.lib.boost.devel/243397). But I haven't heard anything about it lately. Boris

Boris, Boosters, would it be a good idea to add some Boost.Process utilities to Boost.Interprocess? I'm thinking about process launching and pipes. Best Ion

Named pipes are an interprocess mechanism. However named pipes can be synchronous or asynchronous and the asynchronous named pipe methodology is always needed for multi-threaded programs in my experience ( I wrote a named pipe asynchronous mechanism as part of my last consulting job ). Perhaps interprocess can use ASIO for the asynchronous portion of a named pipe implementation.

I was thinking about synchronous utilities, at least in the first integration, but using ASIO would be the way to go for asynchronous versions Best, Ion
