查看错误代码errno是调试程序的一个重要方法。当linuc C api函数发生异常时,一般会将errno变量(需include errno.h)赋一个整数值,不同的值表示不同的含义,可以通过查看该值推测出错的原因。在实际编程中用这一招解决了不少原本看来莫名其妙的问题。比较麻烦的是每次都要去linux源代码里面查找错误代码的含义,现在把它贴出来,以后需要查时就来这里看了。



1-34号错误号是在内核源码的include/asm-generic/errno-base.h定义


35-132则是在include/asm-generic/errno.h中定义


剩下还有一些更大的错误号是留给内核级别的,如系统调用等,用户程序一般是看不见的这些号的,Ubuntu9.10中/usr/src/linux-headers-2.6.31-21-generic/include/linux/errno.h
