This gist is to showcase boost interprocess. Creating a set of classes to create an interface for me to create a shared memory layer for high level languages

	template<size_t BufferSize>
	class SharedMemoryConsumer
	{
	public:
	explicit SharedMemoryConsumer(const std::string& memory_name)
	: name_length_(memory_name.size()),
	shm_(boost::interprocess::open_or_create,memory_name.c_str(),boost::interprocess::read_write)
	{
	shm_.truncate(sizeof(TraceQueue<BufferSize>));
