和前面一个类一样，这两个函数是对我前面那个类的更新！
这次不和那个贴放一块了，我觉得重定位好像还是有点不足的地方，但是已经完全正常，就是不完美！
喜欢的就拿去用吧！
这两类函数可是网络上的稀罕货！
简单先说一下重定位的结构：
地址:DWORD类型
大小:DWORD类型
内容:WORD数组
主要来说内容;
比如,内容的WORD值是3 1 5 0
红色的就是它的类型,后面的"150"就是它要修正的量.
类型如下:
#define IMAGE_REL_BASED_ABSOLUTE 0
#define IMAGE_REL_BASED_HIGH 1
#define IMAGE_REL_BASED_LOW 2
#define IMAGE_REL_BASED_HIGHLOW 3
#define IMAGE_REL_BASED_HIGHADJ 4
#define IMAGE_REL_BASED_MIPS_JMPADDR 5
#define IMAGE_REL_BASED_SECTION 6
#define IMAGE_REL_BASED_REL32 7
//下面的应该不常用的:
#define IMAGE_REL_BASED_MIPS_JMPADDR16 9
#define IMAGE_REL_BASED_IA64_IMM64 9
#define IMAGE_REL_BASED_DIR64 10
#define IMAGE_REL_BASED_HIGH3ADJ 11
//这次我只处理了IMAGE_REL_BASED_HIGHLOW 这个类型,也是最多最常见的.其它的我找了好久也没找到那个文件在用!也就没研究了,这也许是我这个函数的不完美的地方吧!
前面简要说了一下结构我们可以再简要说一下实现:
获得类型的简单方法如下,假设buf是我们需要处理的值.
buf=(buf&0xF000)>>0x0C; //buf就是类型号了.
buf=buf&0x0FFF //就是我们要的偏移量.

这次的代码纯粹是个人杰作!高手们指点一下!呵呵~~~,自我感觉良好!
现在还差什么表没发了！我想除了资源了吧！
