In most operating systems (I think you're talking about Microsoft Windows here?) you can not make function calls between two processes. Each process has it's own memory space and they are isolated from each other.

You can communicate between two processes using inter-process communication mechanisms such as pipes. In Windows you can also use synchronization objects such as events or semaphores between processes. If you elaborate on what you are trying to do I can provide some suggestions.
