| 29 | The <application>Pth</application> package contains a very portable
|

| 30 | POSIX/ANSI-C based library for Unix platforms which provides
|

| 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.
