使用方法首先给信号量初始化赋值,可以根据需要设定需要的值,之前在写项目的过程中用这个控制下载的线程个数. boost::interprocess::interprocess_semaphore m_semaphore(); 然后就是pv操作了,v操作就只有一个post(),post()一次,信号量加1.p操作有三个,看函数名字都很明显知道是什么意思, wait(),try_wait() ,timed_wait(const boost::posix_time::ptime&abs_time). 这…

deque容器为一个给定类型的元素进行线性处理,像向量一样,它能够快速地随机访问任一个元素,并且能够高效地插入和删除容器的尾部元素.但它又与vector不同,deque支持高效插入和删除容器的头部元素,因此也叫做双端队列.deque类常用的函数如下. (1)    构造函数 deque():创建一个空deque deque(int nSize):创建一个deque,元素个数为nSize deque(int nSize,const T& t):创建一个deque,元素个数为nSize,且值均为t…
