Hi
Tayseer,
I
don't agree with that. For any thread there will be a new task struct, and hence
there will be new process ID and all.
for
example I have the following log:

I have an application wherein I have say 10 threads which are created
unconditionally and run a "while(1);".
Will they be shown in the output of ps -A as 10 different processes?
Hi
cause Linux don't differentiate between process and a threads .. they are all tasks
all your threads have the same parent process id "ppid" and share the same process group id "pgid"
hope this helps
