boost::interprocess::shared_memory_object 是Boost.Interprocess 库中用于处理共享内存对象的一个类。它允许进程间通过共享内存进行数据交换,这是进程间通信(IPC)的一种高效方式。通过使用共享内存,多个进程可以访问同一块物理内存区域,从而实现数据的快速共享和传递。
boost::interprocess::shared_memory_object must be passed as the first parameter to the constructor of boost::interprocess::mapped_region. The second parameter determines whether access to the memory area is read-only or read-write. The address and the size of the mapped memory area is written ...
