SimpleIPC

Simple IPC is a Freepascal unit (and Lazarus components) that allows interprocess communication (IPC) between freepascal programs.

It allows two executables to communicate.

Advantages of SimpleIPC

Create communication systems without requiring low level sockets programming of your own. SimpleIPC does the grunt work of IPC for you and makes a nice high level wrapper around lower level IPC mechanisms, so you don't have to program them yourself.

SimpleIPC can be used to communicate between programs to make simple communication systems, plugin systems and much more,

The lazarus help system itself, uses SimpleIPC.

Simple IPC to Other Programming Languages

For IPC between freepascal programs and other programs written in any language (C++, Delphi, GoLang, etc.) see SimpleIPC Library
