Missing header

[jonface]

I was required to add unistd.h to threadpool_test.cpp, not sure if it was just me.

Thanks.

I think you are right. Maybe when I tested this I had sleep() commented out.

Thanks for pointing it out!

Hi, is there a way to start a thread (already finished) second time without calling pthread_create? Or can the finished thread be restarted? Thanks very much!

oh, I find a way:(I am sorry I have no idea about how to format c++ source code)
void* ThreadProcWrapper(void * pParam)
{
Thread* threadPtr = (Thread_) pParam;
while(1)
{
if(threadPtr->m_finished)
{
sleep(1);
continue;
}
threadPtr->m_proc(threadPtr->m_params);
threadPtr->m_finished = true;
}
}
user can access via an Thread interface:
typedef void_ (ThreadProcPtr)(void * pParam);
void Thread::start(const ThreadProcPtr proc , void param);

@nalisaki this would be better discussed in a different forum, however a threadpool is designed for exactly the sort of work you're asking about. The pool itself is a set of threads available to handle any processing given to the threadpool. You should not be directly accessing threads, instead going through the threadpool object. This object will take care of handing off work to individual threads, and storing returned data in an easily accessible way.
You can see this in action in the threadpool_test.cpp code, where a set of four tasks is handed to a threadpool with 2 threads available. The threads process all four tasks without requiring a new thread to be created for each task.
