希望看到这里，你应该对二进制信号量，计数信号量和互斥锁的区别有了清晰的认识。
Hopefully you should now be clear about the core differences between the Binary Semaphore, General (counting) Semaphore and the Mutex.
信号量是又一种以两种风格出现的基本方法：二进制和计数模式。
Semaphores are another type of synchronization primitive that come in two flavors: binary and counting.
