OK. So my first understanding was correct. So I am back to my original question: through which interface should the non-ODP process reach the shared mem? - the ODP API? (which means that non ODP processes/thread could be linked with the ODP lib and however remain non ODP) - or the native OS (e.g. linux syscall)? (meaning that each ODP implementation have to document how to do that)
