这是从伯克利BSD的mbuf中提取的实现代码，如果使用者看过TCP/IP详解2的朋友就会在开篇看到这个代码，

我将其改写，虽然还是没有支持cluster的操作，但是基本可以从中知道这个实现的过程了。

关于Balloc是我为嵌入式系统定制的小型内存块管理系统，用4字节管理128个字节的内存。

MBuffer 是基于其上实现的。（如果没有使用Balloc，dtom将不能得到正确的结果）。-This is the mbuf from the Berkeley BSD implementation of code to extract, if the user read the TCP/IP Xiangjie 2 friends will see this code in the opening chapter, I will be the rewrite, although the cluster or not to support the operation, but the basic can get to know the process of achieving. About Balloc is my custom embedded systems for the small memory block management system, using 4 bytes to 128 bytes of memory management. MBuffer is based on the realization of its. (If you do not use Balloc, dtom will not get the right results).
