hello,
i just did a initial commit of share-mem, a lib dedicated to deal with shared memory.
background : pd / pd~ communication is really slow. by example, having a pd~ patch with 8 audio in and 8 out, use about 50% cpu of a recent computer for each process only to deal with audio communication. sending a large array from one process to the other is almost not possible in RT. This really limit pd~ usability.
Thanks to share memory, communication between process can be greatly improve. This lib is mainly composed of an external, and few abstraction and examples.
Everything look stable, at least on a ubuntu (12.04) and a osX laptop. Implementation follow POSIX standard, so it will unfortunately not work on windows.
everything that I need is there, even if lot's more work could be made. I hope to have user feedback before making more development.
Cheers Cyrille
