在系统转载PE可执行文件时, 往往需要很快找到一些装载所需要的数据结构,如导入表,导出表,资源,重定位表等.

他们保存在IMAGE\_DATA\_DIRECTORY DataDirectory\[IMAGE\_NUMBEROF\_DIRECTORY\_ENTRIES\];中.

typedef struct \_IMAGE\_DATA\_DIRECTORY \{ DWORD VirtualAddress; DWORD Size; \} IMAGE\_DATA\_DIRECTORY, \*PIMAGE\_DATA\_DIRECTORY; \#define IMAGE\_NUMBEROF\_DIRECTORY\_ENTRIES 16
