-ASi Unix Extra Field:
====================
The following is the layout of the ASi extra block for Unix. The
local-header and central-header versions are identical.
(Last Revision 19960916)
Value Size Description
----- ---- -----------
(Unix3) 0x756e Short tag for this extra block type ("nu")
TSize Short total data size for this block
CRC Long CRC-32 of the remaining data
Mode Short file permissions
SizDev Long symlink'd size OR major/minor dev num
UID Short user ID
GID Short group ID
(var.) variable symbolic link filename
Mode is the standard Unix st_mode field from struct stat, containing
user/group/other permissions, setuid/setgid and symlink info, etc.
If Mode indicates that this file is a symbolic link, SizDev is the
size of the file to which the link points. Otherwise, if the file
is a device, SizDev contains the standard Unix st_rdev field from
struct stat (includes the major and minor numbers of the device).
SizDev is undefined in other cases.
If Mode indicates that the file is a symbolic link, the final field
will be the name of the file to which the link points. The file-
name length can be inferred from TSize.
[Note that TSize may incorrectly refer to the data size not counting
the CRC; i.e., it may be four bytes too small.]
