主分区P和扩展分区E加在一起最多只能有4个，且E最多1个，分区号用sdb1~sdb4占据，这是固定的，逻辑分区只能从sdb5开始
 
所以如果用PPPE方式的话，分为
/dev/sdb1
/dev/sdb2
/dev/sdb3
/dev/sdb5
/dev/sdb6
/dev/sdb7
 
如果是PE方式的话]]>https://blog.youkuaiyun.com/douzi24/article/details/6445374https://blog.youkuaiyun.com/douzi24/article/details/6445374douzi24Wed, 25 May 2011 16:51:00 +0800https://blog.youkuaiyun.com/douzi24/article/details/6445355https://blog.youkuaiyun.com/douzi24/article/details/6445355douzi24Wed, 25 May 2011 16:47:00 +0800编码时--使用神秘数值

这种变量的含义被称为“混合耦合”，整数类型耦合了布尔类型
 
变量bytesWritten可能表示写入输出文件的字节数，如为负的话，表示用于输出的磁盘驱动器号
 
这种用法也是不好的。]]>https://blog.youkuaiyun.com/douzi24/article/details/6435519https://blog.youkuaiyun.com/douzi24/article/details/6435519douzi24Fri, 20 May 2011 20:32:00 +0800taylor GA4e，其实就是414e换了个名字而已，3系以上的非缺角型号换了个叫法，14叫GA，12叫GC，16叫GS，10叫DN]]>https://blog.youkuaiyun.com/douzi24/article/details/6426183https://blog.youkuaiyun.com/douzi24/article/details/6426183douzi24Tue, 17 May 2011 10:09:00 +08001. 确保断言使程序终止运行，可以确保每个问题都被强制修复
2. 完全填充所有分配到的内存，这样可以检测到内存分配上的错误
3. 完全填充分配到的流，可以检测到文件格式上的错误
4. 确保每个case分支都能产生严重错误
5. 删除对象前用垃圾数据填满
6. 让程序自动发送错误日志，比如通过电子邮件的方式
