Hi All
Am facing a lot of issue while using interprocess features inside my class file. I am pasting my class file below:
when "mapped_region" is destroyed, then the shared memory is unmapped and you have no acces to it. Make mapped_region a member of your class. void MyClass::createBuffer() { shared_memory_object::remove("test"); shared_memory_object shm(open_or_create, infoBufferName, read_write); shm.truncate(sizeof(ServerDetails)); mapped_region region(shm, read_write); void* addr = region.get_address(); ref=new (addr) Ref; ref->value=50; //Assign the recently created mapped region to the internal member m_member_mapped_region = boost::move(region); } best, Ion
