100: -ASi Unix Extra Field:
101: ====================
102:
103: The following is the layout of the ASi extra block for Unix. The
104: local-header and central-header versions are identical.
105: (Last Revision 19960916)
106:
107: Value Size Description
108: ----- ---- -----------
109: (Unix3) 0x756e Short tag for this extra block type ("nu")
110: TSize Short total data size for this block
111: CRC Long CRC-32 of the remaining data
112: Mode Short file permissions
113: SizDev Long symlink'd size OR major/minor dev num
114: UID Short user ID
115: GID Short group ID
116: (var.) variable symbolic link filename
117:
118: Mode is the standard Unix st_mode field from struct stat, containing
119: user/group/other permissions, setuid/setgid and symlink info, etc.
120:
121: If Mode indicates that this file is a symbolic link, SizDev is the
122: size of the file to which the link points. Otherwise, if the file
123: is a device, SizDev contains the standard Unix st_rdev field from
124: struct stat (includes the major and minor numbers of the device).
125: SizDev is undefined in other cases.
126:
127: If Mode indicates that the file is a symbolic link, the final field
128: will be the name of the file to which the link points. The file-
129: name length can be inferred from TSize.
130:
131: [Note that TSize may incorrectly refer to the data size not counting
132: the CRC; i.e., it may be four bytes too small.]
