C# 線程同步

1.臨界區

Object m_lock_record = new Object();
lock (m_lock_record)
{
   // Critical code section
}

2.事件通知

AutoResetEvent m_auto_event = new AutoResetEvent(true);
void Thread1()
{
    m_auto_event.set();
}
void Thread2()
{
    m_auto_event.WaitOne();
}

3.原子操作

int m_next_video_frame;
Interlocked.Decrement(ref m_next_video_frame);
Interlocked.Increment(ref m_next_video_frame);
