讲述了三为管线的绘制,实现了三为管线的绘制,算法优良,值得下载学习.-described as a three pipeline mapping, for the realization of the three pipeline mapping algorithm fine, it is worth learning download.

程序功能:首先建立一个文件并写到输出管道流,然后用输入管道流读取该文件的内容并写到另一个文件中 -procedures functions : first to establish a paper and wrote pipeline flow then the importation of pipeline flow reading the contents of the document and wrote another document

实现进程的管道通信。用系统调用pipe( )建立一管道，二个子进程P1和P2分别向管道各写一句话： Child 1 is sending a message! Child 2 is sending a message! 父进程从管道中读出二个来自子进程的信息并显示（要求先接收P1，后P2）。 -process of the realization of the communication channel. With system call pipe () to establi
