Hi, Has anyone got any tips on using boost::interprocess::managed_mapped_file with the managed_mapped_file::segment_manager allocators and the boost/interprocess/containers in a memory mapped file which can be used across x64 and arm platforms?

As everything should be using offset pointers, I get the feeling that there should be some way to make this cross platform utopia happen but thought I'd ask before serious tinkering attempts.

Sorry, but allocators and other structures built in shared memory have platform-dependent types and alignment so having a portable memory mapped file is not possible right now. I consider it a very good improvement for Interprocess. The downside is that that would require a total rewrite of the library, since all classes (containers, allocators, memory algorithms) have platform/compiler dependent sizes. Regards, Ion
