一个可行的方式是:使用消息队列传递共享内存中的创建的map的名称,另一方接受到后使用managed_shared_memory打开 #include <boost/interprocess/ipc/message_queue.hpp> 创建消息队列 using boost::interprocess; //Create a message_queue. If the queue exists throws an exception message_queue mq (create_only ...
通过Interprocess,可以实现在共享内存、文件映射中保存vector、map等STL对象,并且可以使用自定义的类,官方文档介绍的也很详细了,下面是几个精简的示例。
由于大小不足以满足分段管理器控制块的要求，它将中止。
