Hi all! I'm a newbie with boost and I'm struggling with objects in shared memory. The following struct is given: struct MyType{ int id; const char* name; const char* rep; MyType(){}; MyType(MyType* const& type){ id = type->id; name = type->name; rep = type->rep; }; Objects of MyType should be shared between processes in shared memory. I have no problem to put and extract the objects from shared space. But I'm struggling with the const char* pointers. I know that pointers are not allowed in shared memory, thats why I tried to realize with boost string by doing the following: typedef boost::interprocess::allocator<char,boost::interprocess::managed_shared_memory::segment_manager> CharAllocator; typedef boost::interprocess::basic_string<char, std::char_traits<char>, CharAllocator> MyString; boost::interprocess::managed_shared_memory segment(boost::interprocess::open_only, "MySharedMemory"); CharAllocator charallocator(segment.get_segment_manager()); struct MyType{ int id; MyString name; MyString rep; MyType(){}; MyType(MyType* const& type){ id = type->id; name = type->name; rep = type->rep; }; But this is not working because the segment and charallocator are not recognized in the struct and if I put boost::interprocess::managed_shared_memory segment(boost::interprocess::open_only, "MySharedMemory"); CharAllocator charallocator(segment.get_segment_manager()); In the struct I get compiler errors. Could anybody help me how I can realize const char* in an object that should be shared? Please help me! Thank you very much! Best regards, Sabine
