在VC ++和Qt应用程序之间使用共享内存进行通信 [英] Communication using Shared Memory between VC++ and Qt applications

问题描述

我正在使用FileMapping在C ++ Windows窗体应用程序中实现共享内存概念，并在Qt应用程序中实现QSharedMemory.

I am using FileMapping for implementing shared memory concept in a C++ windows form application and QSharedMemory in Qt application.

我想在使用QsharedMemory的Qt应用程序中使用FileMapping技术读取由C ++表单应用程序编写的数据.

I want to read data written by C++ form application using FileMapping technique, in Qt application using QsharedMemory.

有可能吗?如果没有，请提出适当的方法来实现此功能.

Is it possible? If not please suggest appropriate methods to implement this feature.

推荐答案

我不确定您的实现细节，但是我建议使用boost::InterProcess -提供了可以在两个过程中使用并随后利用通用代码的机制.

I'm not quite sure of the detail of your implementation, however I would suggest that a better more uniform way to approach this would be by using boost::InterProcess - which provides mechanisms that could be used in both processes and then utilize common code.

另一个原因是该库提供了用于同步的机制以及将来可能有用的其他IPC机制.

The other reason is that the library provides mechanisms for synchronisation and other IPC mechanisms that may be useful in the future.
