今天關注了下最新的C++標準，並試用了下std::thread，lock_guard等功能，還是不錯的。

對於std::thread要join/detach，不然會有異常。

另外當使用socket時網路函式bind應該使用::bind表明是全域性的名稱空間

#include <iostream>
#include <thread>
#include <chrono>
#include <mutex>
#include <vector>

using namespace std;

int globalCount = 10;
std::mutex g_mutex;

void fun1(int n)
{
 std::lock_guard<std::mutex> g(g_mutex);
 globalCount++;
 n++;
 thread::id i = std::this_thread::get_id(); 
 cout << i << " fun1: " << n << endl;

}

void fun2(int& n)
{
 n++;
 thread::id i = std::this_thread::get_id(); 
 cout << i << " fun1: " << n << endl;
}

int _tmain(int argc, _TCHAR* argv[])
{
 int n1 = 100;
 int n2 = 100;
 std::thread t1(fun1, n1);
 std::thread t2(fun2, std::ref(n2));
 t1.join();
 t2.join();
 cout << "Main:" << n1 << " , " << n2 << endl;

 std::vector<std::thread*> threadList;
 for(int i = 0; i < 20; i++)
 {
  std::thread* t = new std::thread(fun1, i);
  threadList.push_back(t);
 }
 for(int i = 0; i < 20; i++)
 {
  threadList[i]->join();
 }

 std::this_thread::sleep_for(std::chrono::seconds(1));
 cout << endl << globalCount << endl;

 cout << "press any key to exit..." << endl;
 char c;
 cin >> c;
}
