| H A D | c_waiting.md | 11 ## 一. wait_queue等待队列
13   wait_queue是一种进程同步机制，中文名为“等待队列”。它可以将当前进程挂起，并在时机成熟时，由另一个进程唤醒他们。
15   当您需要等待一个事件完成时，使用wait_queue机制能减少进程同步的开销。相比于滥用自旋锁以及信号量，或者是循环使用usleep(1000)这样的函数来完成同步，wait…
18 `wait_queue.h`中的等待队列的实现并没有把队列头独立出来，同时没有考虑为等待队列加锁。所以在后来的开发中加入了`wait_queue_head_t`的队列头实现，实质上就是链表+自旋锁。…
29   要使用wait_queue，您需要`#include<common/wait_queue.h>`，并创建一个`wait_queue_node_t`类型的变量，作为等待队列的头…
49 …; 函数`wait_queue_init(wait_queue_node_t *wait_queue, struct process_control_block *pcb)`提供了初始化…
51   当您初始化队列头部时，您仅需要将wait_queue首部的结点指针传入，第二个参数请设置为NULL
90    等待队列头的使用逻辑与等待队列实际是一样的，因为他同样也是等待队列的节点(仅仅多了一把锁)。且wait_queue_head的函数基本上与wait_queue一致，只不过多…
92    同时，wait_queue.h文件中提供了很多的宏，可以方便您的工作。
