linux下面的文件锁和信号量的程序

对读入的某个文本文件input.txt中，拆出英文单词，输出一个按字典顺序排列的单词表，结果输出在文本文件output.txt中，每个单词一行，并在单词后输出该单词出现的个数，两个字段之间用逗号分隔。约定单词仅由英文字母组成，单词间由非英文字母分隔，相同单词只输出一个，大小写不区分。 利用二叉树实现-the right time to a text file input.txt, divestment English words, Output by an order of the dictionary word list, the result output in a text file output.txt. Every word here, and the output of the word after word of the number, between two fields separated by a comma. Agreed only by the words in alphabetical composition, word by non-alphabetic segregation, the same word is only one output, distinction is not case. Achieved using binary tree

多线程程序作为一种多任务、并发的工作方式，有以下的优点： 　　1) 提高应用程序响应。这对图形界面的程序尤其有意义，当一个操作耗时很长时，整个系统都会等待这个操作，此时程序不会响应键盘、鼠标、菜单的操作，而使用多线程技术，将耗时长的操作（time consuming）置于一个新的线程，可以避免这种尴尬的情况。 　　2) 使多CPU系统更加有效。操作系统会保证当线程数不大于CPU数目时，不同的线程运行于不同的CPU上。 　　3) 改善程序结构。一个既长又复杂的进程可以考虑分为多个线程，成为几个独立或半独立的运行部分，这样的程序会利于理解和修改。 -multithreaded process as a multi-task, complicated by the way, has the following advantages : 1) improve application response. This graphical interface is especially meaningful, when a very long time-consuming operation, the entire system will wait for the operation, this procedure will not respond to keyboard, mouse, the menu of operations, and the use of multithreading technology, long will be time-consuming operation (time consuming) under a new thread, avoided this embarrassing situation. 2) multi-CPU system more effective. When the operating system would ensure that not more than a few threads CPU number of different threads running on different CPUs. 3) to improve program structure. A long and complex
