All,
we are currently doing our first steps with C on z/OS (MVS Environment).
Now,.... everything is somewhat different than under UNIX or Windows.
For example the call of "fork()" is somewhat strange. In my
multithreaded application I can't use fork. I can't use subtasks if I
use threads. fork() somehow works, but I can't see the SYSOUT/SYSPRINT
of the forked process.
The manual is somehow confusing - .... for me.
Now, I guess everything would become clearer if I would know exactly all
the magic of address spaces, processes, thraeds, tasks, subtasks and so
on. For example, just a few minutes ago I've read in an IBM manual that
there exist single-process address spaces and multiple-process address
spaces (never heard about that before). Now.... is is task a process? If
I use subtasks - do I use multiple-process address spaces? What is the
difference between a subtask and a thread? What is the difference
between a job and a started task?
So, there are many many questions I need/want to understand all this
stuff better.
Could someone tell me what IBM Manual would be a good choice to start?
I've tried POP (Principles of Operation) but this wasn't the right one...
Thank you very much,
Michael
