Hi to all, I've just uploaded a new version of Shmem. Changes and new features: New feature: -> Apart from shared memory, all Shmem classes (containers, allocators, utilities) can be used to allocate all resources in a user defined fixed size buffer. This way, all resources will be allocated in a single buffer that could be easily serialized (Thanks to Martin Adrian for the idea). Changes: -> Bug fixes in code, comments and documentation -> Passed all tests in linux (suse 9.2-gcc 3.4.1) (except for shared_read_write_mutex that fails) -> Changed allocator swapping to the recommended solution in the paper "Issue 431: Swapping containers with unequal allocators" -> Some corrections for exception-safe constructors in containers (not that I think they are perfect but much better than before). -> Some EBO optimization in templatized mutexes when using null_mutex. Thanks to Pavel for his comments and advices. Regards, /Ion
