Post Making a program "talk" to another

In the game C-Robots (, the main program seems to wait for one of the robot programs to startup and talk to it. Im not asking how he did that, but what he used to do that. Im assuming theres some lib that comes with linux that lets you do that.

He compiles his robots with the librobot.a. He hasn't included the source code to that library but from what I can see he just uses normal network sockets to send data back and forth.

I haven't seen that program.

but you're looking into IPC ( inter-process communication ). There are tons of books on this. A very good one is the Stevens.

IPC falls under many catagories. From most effecient but difficult to program Memory mapped IO ( mmap ), where separate process share memory by sharing a region of memory. To very simple UNIX domain sockets, where the processes share a special socket file to exchange information. And finally UNIX PIPES, where file descriptors and normal file read()/write() functions are used to share information.
