描述了一个用于比较Linux系统中可靠信号与不可靠信号实验的设计 .首先 ,简要描述了UNIX Linux信号机制以及不可靠信号和可靠信号 ,然后根据不可靠信号与可靠信号的特点给出了几个用于比较二者差别的程序 ,接着考察了在使用libc6的Linux系统中无法正确观察到不可靠信号实验现象的问题并给出了一个解决方案This paper describes an experiment on comparing unreliable signal with reliable signal in Linux. First, a brief review of signal in UNIX/Linux and the difference between unreliable signal and reliable signal was put forward. Then we presented some programs used to compare unreliable signal with reliable signal according to their points. At last we make an investigation of the problem that the phenomenon of unreliable signal did not shown correctly in Linux system using libc6 and gave a resolution
