ntfstypes.h

一个linux下NTFS文件格式源代码

/*
 *  types.h
 *  This file defines four things:
 *   - generic platform independent fixed-size types (e.g. ntfs_u32)
 *   - specific fixed-size types (e.g. ntfs_offset_t)
 *   - macros that read and write those types from and to byte arrays
 *   - types derived from OS specific ones
