看一下UNIX系统中的进程和Mach的任务和线程之间的关系。在UNIX系统中,一个进程包括一个可执行的程序和一系列的资源,例如文件描述符表和地址空间。在Mach中,一个任务仅包括一系列的资源;线程处理所有的可执行代码。一个Mach的任务可以有任意数目的线程和它相关,同时每个线程必须和某个任务相关。和某一个给定的任务相关的所有线程都共享任务的资源。这样,一个线程就是一个程序计数器、一个堆栈和一系列的寄存器。所有需要使用的数据结构都属于任务。一个UNIX系统中的进程在Mach中对应于一个任务和一个单独的线程。
-look at the UNIX System and the process of Mach"s mandate and the relationship between the threads. In UNIX systems, a process includes an executable program and a range of resources, such as file descriptors table and address space. In Mach, a task only a series of resources; Threads handle all the executable code. A Mach task can have any number of threads and its associated, and each one must thread related tasks. And to a certain set of tasks related to the threads are sharing all the resources. Thus, a thread is a program counter, a stack, and a series of registers. All need to use the data structures are covered by the mandate. A UNIX system in the process of Mach which corresponds to a mandate and a separate thread.

功能介绍:有些软件在运行中要将某些文件压缩成压缩文件。自己写压缩过程未免太麻烦了,
虽然有很多免费的源代码类可以使用,还要看代码的使用方式,一个不小心就不一定很正常了。
我的做法是调用现有的压缩文件来完成压缩功能。用等待进程结束的方法实现压缩。
完成后再作后面的其他工作。
本程序旨在演示启动和等待进程结束的方式调用其他程序的方法。
-functional presentations : Some software in the operation of certain documents should compressed into compressed files. , Wrote the compression process would be too troublesome, although there are many free source code can use category, but also the use of code, a careless It is not the normal. My approach is to call the compressed files to complete compression. The process used to wait for the end of the compression method. Upon the completion of the back for the other work. This procedure aims to demonstrate the process of initiating and wait for the end of the call other procedures.
