    |The unit for the st_blocks member of the stat structure is not
    |defined within IEEE Std 1003.1-2001. In some implementations it
    |is 512 bytes. It may differ on a file system basis. There is no
    |correlation between values of the st_blocks and st_blksize, and
    |the f_bsize (from <sys/statvfs.h>) structure members.
