如何在 Windows 服务和进程之间使用命名互斥锁和共享内存? [英] How to use named mutex and shared memory between a windows service and a process?

问题描述

我有一个用 C++\MFC 编写的代码，它作为 Windows 服务和(普通)C++\MFC Windows 进程运行 - 现在我希望使用命名互斥和共享内存(文件映射)在两者之间进行通信.

I'm have a code written in C++\MFC that is run as a Windows Service and a (normal) C++\MFC Windows process - now I wish to communicate between the two using named Mutex and Shared memory (File mapping).

这怎么可能?

推荐答案

这取决于您的沟通需求.通常，服务创建互斥锁和共享内存，客户端打开它们并执行操作.OutputDebugString() 是使用互斥锁和共享内存(以及一些事件)的 IPC 的经典示例.这里详细介绍了 OutputDebugString() 的工作原理；你可以做类似的事情.

It depends on your communication requirements. Generally the service creates the mutex and shared memory and the clients open them and do stuff. OutputDebugString() is a classic example of IPC using a mutex and shared memory (and some events). Here is a detailed examination of how OutputDebugString() works; you could do something similar.
