一.Mutual exclusion
A mutex object facilitates protection against data races and allows safe synchronization of data between execution agents (30.2.5).

互斥对象有助于防止数据竞争，允许在执行的数据之间安全同步，，允许安全的同步执行中的数据

#include <thread>
#include <mutex>
using namespace std;

std::thread SB(&SUSAKE::Test, this);
SB.detach();

void Susake::Test() {
    while(1) {
        mutex.lock();
        if(t > 0) {
            printf("%d", t--);
            mutex.unlock();
        }
        else {
            mutex.unlock();
            break;
        }
    }
}

二.Condition variables

Condition variables provide synchronization primitives used to block a thread until notified by some other thread that some condition is met or until a system time is reached.
