|

31 | non-preemptive priority-based scheduling for multiple threads of

32 | execution (multithreading) inside event-driven applications. All
|

33 | threads run in the same address space of the server application, but

34 | each thread has its own individual program-counter, run-time stack,
|
---|
35 | signal mask and errno variable.
