每辆车只计数到达50,增量计数信号量(一次)。
Each car simply counts up and upon reaching 50, increments the counting semaphore (once) too.
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.
在第一部分中,我们回顾了二值信号量与计数信号量的历史,并且讨论了信号量的几个问题。
In Part 1 of this series we looked at the history of the binary and counting semaphore, and then went on to discuss some of the associated problem areas.
这个函数会挂起调用线程,直到这个信号量有一个非空计数为止。
This function suspends the calling thread until the semaphore has a non-zero count.
可以通过使用semctl将信号量计数器的初始值设置为0来获得信号量。
A semaphore can be owned by setting the initial count of the semaphore to 0 using semctl .
LinuxPOSIX信号量也是一些计数器变量,可以用来在Linux上实现Windows上的信号量功能。
Linux POSIX semaphores are count variables and can be used to achieve the Windows functionality of semaphores on Linux.
尽管POSIX信号量是计数器信号量,但是当这个计数器被设置为1时,它们可以提供与Windows事件对象相似的功能。
POSIX semaphores are count semaphores, but when the count is set to 1 they provide similar functionality to the Windows event object.
value(信号量计数器)是这个信号量的初始值。
Value (semaphore count) is the initial value of the semaphore.
如果服务器上没有出现任何信号量超时,统计数据Sem . timeouts就不会出现在Statrep . nsf中。
The statistic Sem.timeouts will not appear in Statrep.nsf if the server has not experienced any semaphore timeouts.
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.
文中重点分析了采用计数器信号量解决多进程同步通信,即生产者—消费者问题。
But the focus in this paper is the application of counting semaphore in VxWorks, which can be used in the Producer_Consumer problem to solve the data synchronism in multi process communication.
以指定的次数退出信号量并返回前一个计数。
Exits the semaphore a specified number of times and returns the previous count.
在信号计数器信号量的方法和整数参数之间的理解差异?
Difference in understanding between semaphore counter and semaphore methods integer parameter?
冬季的侧柏切片,其超声发射信号量和持续时间均比夏季的少,幅度、振铃计数和上升时间差别不大。
The amount of signals and duration were smaller than in summer, and amplitude, rise-time, ringing counts were not very different.
