The relationship of the two applications to call functions?
The application has A Windows and Linux (closed source code) that allows you to plug custom plug-ins .dll and .so. I need to link this app with the app NodeJS (open source) plugin. That is, I need to have the app on NodeJS could call the function in the plug-in application A, and turn to the application A can call a function in the app on NodeJS. You will need some interface for communication between applications. To the end of the two applications to get one. Of course you need to pass some parameters in these fucntion. How it is implemented and on what basis?
