Oh actually I just want one of the 6 programs to get input and output from the screen. So...this is what you mean? the communication?
Oh but...can't this C program just output something to the screen and then get it back, and having all these done inside the C program itself?
Or you're saying I just have to do the pipes in order to do this?
Bcoz I thought the inputs and outputs can all be done inside the C program. And the
GUI program (windows
API) is simply creating the child windows and then execute the C programs. So it is not that easy?
