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

Linux下的声音设备编程比大多数人想象的要简单得多。一般说来，我们常用的声音设备是内部扬声器和声卡，它们都对应/dev目录下的一个或多个设备文件，我们象打开普通文件一样打开它们，用ioctl（）函数设置一些参数，然后对这些打开的特殊文件进写操作。-Linux Generally speaking, we used the voices of internal equipment and audio speakers, which corresponds to/dev directory of one or more equipment, we like to open the file as they opened with ioctl () function set some parameters, then open these documents into the special write .
