管道（Pipe）实际是用于进程间通信的一段共享内存，创建管道的进程称为管道服务器，连接到一个管道的进程为管道客户机。一个进程在向管道写入数据后，另一进程就可以从管道的另一端将其读取出来。匿名管道（Anonymous Pipes）是在父进程和子进程间单向传输数据的一种未命名的管道，只能在本地计算机中使用，而不可用于网络间的通信。-pipes (Pipe) for the actual inter-process communication for shared memory, the creation of a process known as the Pipeline Pipeline server, connecting to a pipe to channel the process of the client. In a process to write to the pipeline, another process can pipeline from the other end to read out. Anonymous pipes (Anonymous Pipes) is the father of the child process and the process of one-way transmission of data not a Naming the channel and the local use of the computer, and may not be used for inter-network communications.
