Terminate a process from End Event of a sub-process

Question

Hi, 
 Let's admit I have 3 process. Process A calls a sup-process B wich calls it self another process C. 
 If a fonctionnal error is raised from C, is there any way to stop definitively B and A (from C) ? 
 
 Or I have to deal with an error code below to push up the information to the parent process of each process ? 
 Process C met an error, we set pv!error=true and terminate the process 
 In Process B we test the return value from C, if true, we set pv!error=true and terminate the process 
 In Process A we test the return value from B, if true, we terminate process

They way you explained, is the way I would go as well. If a process is interested in the result of a subprocess it called, it needs to implement some logic to check for it and act accordingly.
