The issue names no repository files or tests. Start by reviewing the N-API entry point and the C++ DLL, shared-memory file mapping, and separate-process communication described in the issue. Done would require a clearly scoped example or documented support path for the requested Node.js-to-C++ process communication.

Descrizione

Hello;
I want to send and receive data from a game simulation in a seperate C++ process, from Node.js. I want Node.js to connect to the outside internet and Node.js will need to communicate with a game simulation run in a seperate process.

Memory sharing seems to be the fastest way to do interprocess communication. Its faster than pipes or sockets, so I want to use memory sharing to do the IPC. I was thinking that N-API could be used to do this.

The question is can I use N-API to connect to a C++ DLL and create a shared memory object (file map). The DLL will be loaded into the Node.js process and it will load a DLL that has already been loaded by the C++ executable. The the file mapping of the system pagefile will be loaded into both the Node.js process and the seperate C++ process. To send something from Node.js to the C++ process, I would just call and required funtions., which would call a function in the DLL that wrote to the share memory map file. After the shared memory has been written to the, it would unblock a handle that the server has access to. The C++ process could then read the shared memory. Has anyone tried this? I mean N-API allows on to call C++ ftns in a DLL, but to call ftns in a seperate process is what I want.
