An unintelligent process that continues forever in the face of failures can generate thousands of retries per second; if your driver prints a "my device is broken" message every time, it could create vast amounts of output and possibly hog the CPU if the console device is slow－to interrupts can be used to driver the console, even if it is a serial port or a line printer.

一个设计糟糕的进程在遇到错误时会进入死循环状态，每秒中内会对函数进行上千次的重调；如果你的驱动程序每次都显示"设备损坏"的消息，那将会产生大量的输出信息，并且当控制台设备的是低速运行设备时有可能会独占 CPU ，即使它是一个串口或是一个行式打印机。

a mandatory testing device to prevent drunk driving is proposed.it can mandatorily test whether and how much a driver or a sailor on watch drunk.only when the alcoholicity of the exhalation breathed out by the people tested is normal,small type or automobiles can startup,the person on watch of a large ship can register as working.otherwise,if the alcoholicity is overproof,small type ships or automobiles can't startup,and neither does the device allow the person on watch register as working and it can inform the captain via alarm.in this way,drunk driving problem can be solved effectively only by setting a simple device.

该装置具有强制检测机动车驾驶员和船舶值班人员饮酒状态的功能，当被测人员呼出的气体酒精含量正常时，机动车或者小型船舶可以启动，大型船舶的值班人员可以记录为值班；当被测人员呼出的气体酒精含量超标时，机动车或者小型船舶无法启动，大型船舶的值班人员则不能记录为值班，同时可以通过报警器通知船长。这样，仅通过安装使用这样一个简单的装置，就有效地解决了酒后驾驶机动车和船员酒后值班的问题。
