linux错误码大全
查看错误代码errno是调试程序的一个重要方法。当linuc Capi函数发生异常时,一般会将errno变量(需includeerrno.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。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
