| -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.] | |
