Sequentially executed processes
We have the following situation in which 4 processes must be executed one after the other A -> B -> C -> D. After process A has finished then process B has to stat automatically and so on.
The information gathered in process A must be available at process B and so on until the last process.
How to make available collected data from one process (process A) to the beginning of the next one (process B)?
The way to go here is by using signal events? Does the processes have to share the same process entity?
