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。
Notice that in System V semaphores, key is used to uniquely identify the semaphore; in Windows, the semaphore is identified by a name.
注意，在Systemv信号量中，key被用来惟一标识信号量；在Windows中，信号量是使用一个名称来标识的。
This is the code used to create the System V semaphore: int semget (key_t key, int nsems, int semflg). Following are the attributes to this code.
用来创建Systemv信号量使用的代码是：intsemget (key_t key, intnsems, intsemflg)。
