Where to get simple Boost Thread Management example?

Question

So I have a simple cpp file. Only one with one main function and 3 int a-la public variables. like:

   int a;
   int b;
   int c;
   void main()
   {
      s         


        

Answer 1

There is a series of articles starting here that should give you some initial pointers. The writer is responsible in large part for shepherding boost.thread into C++0x.

List of the articles:

Multithreading in C++0x Part 1: Starting Threads

Multithreading in C++0x Part 2: Starting Threads with Function Objects and Arguments

Multithreading in C++0x Part 3: Starting Threads with Member Functions and Reference Arguments

Multithreading in C++0x Part 4: Protecting Shared Data

Multithreading in C++0x Part 5: Flexible locking with std::unique_lock<>

Multithreading in C++0x part 6: Lazy initialization and double-checked locking with atomics

Multithreading in C++0x part 7: Locking multiple mutexes without deadlock

Multithreading in C++0x part 8: Futures, Promises and Asynchronous Function Calls

Answer 2

Here is a small and simple example. It's tried and seems to work fine.

#include <iostream>
#include <boost/thread.hpp>

namespace this_thread = boost::this_thread;

int a = 0;
int b = 0;
int c = 0;

class BaseThread
{
public:
    BaseThread()
        { }
    virtual ~BaseThread()
        { }

    void operator()()
    {
        try
        {
            for (;;)
            {
                // Check if the thread should be interrupted
                this_thread::interruption_point();

                DoStuff();
            }
        }
        catch (boost::thread_interrupted)
        {
            // Thread end
        }
    }

protected:
    virtual void DoStuff() = 0;
};

class ThreadA : public BaseThread
{
protected:
    virtual void DoStuff()
    {
        a += 1000;
        // Sleep a little while (0.5 second)
        this_thread::sleep(boost::posix_time::milliseconds(500));
    }
};

class ThreadB : public BaseThread
{
protected:
    virtual void DoStuff()
    {
        b++;
        // Sleep a little while (0.5 second)
        this_thread::sleep(boost::posix_time::milliseconds(100));
    }
};

int main()
{
    ThreadA thread_a_instance;
    ThreadB thread_b_instance;

    boost::thread threadA = boost::thread(thread_a_instance);
    boost::thread threadB = boost::thread(thread_b_instance);

    // Do this for 10 seconds (0.25 seconds * 40 = 10 seconds)
    for (int i = 0; i < 40; i++)
    {
        c = a + b;
        std::cout << c << std::endl;

        // Sleep a little while (0.25 second)
        this_thread::sleep(boost::posix_time::milliseconds(250));
    }

    threadB.interrupt();
    threadB.join();

    threadA.interrupt();
    threadA.join();
}
