Subject: Re: [OMPI users] Object Send Doubt

Hi Carlos,
simply you can send all object's field and rebuild new object in destination
process. Maybe, you have to delete old object in source process. Remember
that you can't send address (eg: pointers) because they refera in local
memory. If you want to do "deep copy" of object, you have to send the entire
structures pointed to.
