child_process.spawn() with 'ipc': has JSON built-in? about help HOT 4 CLOSED

By checking the code it seems that ' ipc' assumes JSON based messages with no line break (just one at the end that signals end of message).

This is clearly designed for spawning a Node subprocess. What about if my subprocess is not a Node program but a C program? What should I expect in the C side? Which kind of messages should I send from C side? Shouldn't this be documented?

It's really only intended for communication between node processes but if your C program speaks newline-delimited JSON, there's no reason it wouldn't work.

The 'ipc' part is tricky on Windows; the C program needs to know about the ad hoc protocol for sending over handles (unless you let libuv handle that, of course.)

Thanks a lot. Anyhow I'll feel more comfortable with a simple pipe :)

@ibc did you find a good solution to this? I think IPC can be implemented with pipes. I just don't know how Node.js implements IPC, I think there is more than one way to do IPC of course, just not sure how Node.js does it.
