模块定义文件格式以及memory share segments

c++看dynamic linking的 module define format:

 LIBRARY GlobalHookDll   //dll名称
2 EXPORTS
3 SetHook        @3
4 SEGMENTS               //共享memory段
5 .MySec    READ WRITE SHARED   

 等价于下面：

 

//use share memory
#pragma data_seg(".MySec")  //the name of setion's length must less than 8
HWND g_hWnd = NULL;
#pragma data_seg()

/*#pragma comment(linker,"/section:.MySec,RWS")*/
