关于文件映射的问题(MapViewOfFile)(50分)

各位好：<br>&nbsp; 我的问题是怎样用Win32Api- MapViewOfFile 从文件的指定位置进行映射。<br>谢了！

LPVOID MapViewOfFile(<br><br>&nbsp; &nbsp; HANDLE hFileMappingObject, // file-mapping object to map into address space &nbsp;<br>&nbsp; &nbsp; DWORD dwDesiredAccess, // access mode <br>&nbsp; &nbsp; DWORD dwFileOffsetHigh, // high-order 32 bits of file offset <br>&nbsp; &nbsp; DWORD dwFileOffsetLow, // low-order 32 bits of file offset <br>&nbsp; &nbsp; DWORD dwNumberOfBytesToMap // number of bytes to map <br>&nbsp; &nbsp;<br><br>在建立视图时是允许指定映射的偏移量的啊。
