(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.] */ typedef struct _phar_zip_extra_field_header { char tag[2]; char size[2]; } phar_zip_extra_field_header; typedef struct _phar_zip_unix3 { char tag[2]; /* 0x756e Short tag for this extra block type ("nu") */ char size[2]; /* TSize Short total data size for this block */ char crc32[4]; /* CRC Long CRC-32 of the remaining data */ char perms[2]; /* Mode Short file permissions */ char symlinksize[4]; /* SizDev Long symlink'd size OR major/minor dev num */ char uid[2]; /* UID Short user ID */ char gid[2]; /* GID Short group ID */ /* (var.) variable symbolic link filename */ } phar_zip_unix3; /* See https://libzip.org/specifications/extrafld.txt */ typedef struct _phar_zip_unix_time { phar_zip_extra_field_header header; char flags; /* flags 1 byte */ char time[4]; /* time in standard Unix format 4 bytes */ } phar_zip_unix_time; typedef struct _phar_zip_central_dir_file { char signature[4]; /* central file header signature 4 bytes (0x02014b50) */ char madeby[2]; /* version made by 2 bytes */ char zipversion[2]; /* version needed to extract 2 bytes */ char flags[2]; /* general purpose bit flag 2 bytes */ char compressed[2]; /* compression method 2 bytes */ char timestamp[2]; /* last mod file time 2 bytes */ char datestamp[2]; /* last mod file date 2 bytes */ char crc32[4]; /* crc-32 4 bytes */ char compsize[4]; /* compressed size 4 bytes */ char uncompsize[4]; /* uncompressed size 4 bytes */ char filename_len[2]; /* file name length 2 bytes */ char extra_len[2]; /* extra field length 2 bytes */ char comment_len[2]; /* file comment length 2 bytes */ char disknumber[2]; /* disk number start 2 bytes */ char internal_atts[2]; /* internal file attributes 2 bytes */ char external_atts[4]; /* external file attributes 4 bytes */ char offset[4]; /* relative offset of local header 4 bytes */ /* file name (variable size) */ /* extra field (variable size) */ /* file comment (variable size) */ } phar_zip_central_dir_file; typedef struct _phar_zip_dir_signature { char signature[4]; /* header signature 4 bytes (0x05054b50) */ char size[2]; /* size of data 2 bytes */ } phar_zip_dir_signature; /* unused in this release */ typedef struct _phar_zip64_dir_end { char signature[4]; /* zip64 end of central dir signature 4 bytes (0x06064b50) */ char size1[4]; /* size of zip64 end of central directory record 8 bytes */ char size2[4]; char madeby[2]; /* version made by 2 bytes */ char extractneeded[2]; /* version needed to extract 2 bytes */ char disknum[4]; /* number of this disk 4 bytes */ char cdir_num[4]; /* number of the disk with the start of the central directory 4 bytes */ char entries1[4]; /* total number of entries in the central directory on this disk 8 bytes */ char entries2[4]; char entriestotal1[4]; /* total number of entries in the central directory 8 bytes */ char entriestotal2[4]; char cdirsize1[4]; /* size of the central directory 8 bytes */ char cdirsize2[4]; char offset1[4]; /* offset of start of central directory with respect to the starting disk number 8 bytes */ char offset2[4]; /* zip64 extensible data sector (variable size) */ } phar_zip64_dir_end; /* unused in this release */ typedef struct _phar_zip64_dir_locator { char signature[4]; /* zip64 end of central dir locator signature 4 bytes (0x07064b50) */ char disknum[4]; /* number of the disk with the start of the zip64 end of central directory 4 bytes */ char diroffset1[4]; /* relative offset of the zip64 end of central directory record 8 bytes */ char diroffset2[4]; char totaldisks[4]; /* total number of disks 4 bytes */ } phar_zip64_dir_locator; typedef struct _phar_zip_dir_end { char signature[4]; /* end of central dir signature 4 bytes (0x06054b50) */ char disknumber[2]; /* number of this disk 2 bytes */ char centraldisk[2]; /* number of the disk with the start of the central directory 2 bytes */ char counthere[2]; /* total number of entries in the central directory on this disk 2 bytes */ char count[2]; /* total number of entries in the central directory 2 bytes */ char cdir_size[4]; /* size of the central directory 4 bytes */ char cdir_offset[4]; /* offset of start of central directory with respect to the starting disk number 4 bytes */ char comment_len[2]; /* .ZIP file comment length 2 bytes */ /* .ZIP file comment (variable size) */ } phar_zip_dir_end;
