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 ...
是一个出现在编程中的错误,表示在当前环境中无法导入shared_memory模块或函数。 共享内存是一种进程间通信的方式,它允许多个进程共享同一块内存区域,从而实现数据共享。在某些编程场景中,我们可...
确保你的代码中正确地包含了boost::interprocess::shared_memory所需的头文件。例如: cpp #include <boost/interprocess/shared_memory_object.hpp> #include <boost/interprocess/mapped_region.hpp> 这些头文件通常位于Boost库的boost/interprocess目录下。 验证操作系统是否支持共享内存,以及是否有权限...
