Inter-process Networking

[Curt Carpenter]

I have four independent lazarus programs (instruments) running on my PC, and they all need to be able to communicate with a common lazarus "control panel" program that coordinates their work.  I can implement the communications using the SimpleIPCServer and SimpleIPCClient components, but this seems overly complicated.  Is there a better way to implement a "wheel and spoke" communication network (https://www.toppr.com/ask/question/explain-wheel-spoke-network-in-communication/)  among a collection of running processes?

You could try ZeroMQ.

• Guide covering all kinds of communication patterns
• FPC examples, comes with FFI binding
• Delphi examples
• Another older FPC FFI binding

Thanks PierceNg -- that looks very interesting.  I'll spend some time studying the guide over the next few days.  Probably overkill to my simple topology and needs, but looks worth studying.
