IPC: Starting A Server By A Client

[Arnim Schachtschabel]

Hello Community,

I would like to let two local applications communicate with each other. A client retrieves informations from the server (a simple IPC).

The implementation itself is no big deal (it's a socket server).

I did not get out yet, how I can have the client start the server out of its own process. Otherwise the user would have to start the client and the server manually. He then would have to take care to start the server first. I would like to cloak this process for the user, as he should not be bothered with the technical details. In the documentation this is mentioned, of cause.

Is it possible?
Can you help me out?

Kind regards
Arnim

You can use a Sys.command to launch the server.

Depending on what system you are on, you could use this command to start a shell process with the "&" to launch in the background, and possibly a output-redirect to log file if you are keen.

There's also sys.io.Process which may be more suitable. You can then use the child processes stdio streams to communicate with it.

Best,

Juraj
