passing a value from one code to another

[John Karror]

It's my first time writing a real program (UI and stuff)

I am using GTK+ with C. My program is written in C++, and I also have some simple ones in python.

I simply want to do the following:

-Run C (GTK) program (C running)
---pass a value from C (GTK) to C++ (C waiting, C++ running)
---pass calculation values from C++ to python (C waiting, C++ waiting, python running)
---pass values from C++ to C (C waiting, C++ running)
-(C running) ....

I think you get the point, I don't know how to glue my program ^^". I tried to read from the Internet but I didn't understand. I think they refer to such thing as "pipe"

Any thoughts? ^^"

You're asking about "inter process communication".
