Hello, in my program a shared memory object is created by: managed_windows_shared_memory shm (open_or_create, "MySharedMemory", shm_size); The problem is that calling to 'shm' object methods, the program cannot detect - was shared memory actually created or it was opened only? Looks like somewhere inside 'managed_windows_shared_memory' class this information is availble but not exposed via its public interface. May it be fixed? Regards, Alex
