在Boost库中,可以使用boost::iostreams::mapped_file类来实现内存映射文件的读写操作。该类提供了简单易用的接口,可以方便地进行文件的读写操作。 下面是使用Boost在C++中读/写内存映射文件的示例代码: 代码语言:cpp 复制 #include<boost/iostreams/device/mapped_file.hpp>#include<iostream>intmain(){// 创建一...

此功能被封装在 anonymous_shared_memory() 函数中,该函数会返回一个 mapped_region 对象,该对象持有一个可以被相关进程共享的匿名共享内存段。 #include <boost/interprocess/anonymous_shared_memory.hpp> #include <boost/interprocess/mapped_region.hpp> #include <iostream> #include <cstring> int main () {...
