自己写的CONDITION_VARIABLE和SRWLock配合使用的例子

        其中先启动TimeTrigger线程，用的是排他锁，另外两个线程用的是共享锁，可以并发。整体来看就是TimeTrigger完后，Thread1和Thread2并发一次。主要在于用一个线程控制另外多个线程的并发，尝试开设线程之间地位不平等时，线程的并发处理，如果加锁加的好的话，是可以达到效果的。

        WakeAllConditionVariable(&cv);

    }

    int a  = 0;

        a++;

        printf("thread1:  a = %d\n",a);

        ReleaseSRWLockShared(&slock);

    }

}

 

DWORD WINAPI Thread2(LPVOID)

{

    int b = 0;

    while(true)

    {

        AcquireSRWLockShared(&slock);

        SleepConditionVariableSRW(&cv,&slock,INFINITE,CONDITION_VARIABLE_LOCKMODE_SHARED);

        b++;

        printf("thread2:  b = %d\n",b);

        ReleaseSRWLockShared(&slock);

    }

}
