interlocking system of semaphore 臂板电锁器联锁
When a semaphore protects a large amount of data, assuming one or more tasks USES it on a write basis, the semaphore becomes a bottleneck within the system.
在一个信号量保护大量数据时，如果一个或多个任务使用它进行写操作，这个信号量就会成为系统瓶颈。
In order to initialize the semaphore-set data structure, use the semctl system call with the IPC_SET command.
为了对信号量集数据结构进行初始化，可以使用IPC_SET命令来调用semctl系统调用。
A semaphore is to your system what a traffic signal is to an intersection: a mechanism that keeps things running smoothly.
信号量对于系统的作用就像是十字路口的信号灯：一种保持系统运行顺畅的机制。
