Simple example using threadpool

Introduced classes

class HWTask

pthreads :: HWTask

Task printing "hello world" on standard output

Redefined classes

redef class Sys

pthreads :: threadpool_example $ Sys

The main class of the program.

All class definitions

class HWTask

pthreads $ HWTask

Task printing "hello world" on standard output
redef class Sys

pthreads :: threadpool_example $ Sys

The main class of the program.
