File: tar.egg.info, Node: Reading, Next: Writing, Prev: Documentation, Up: Top 3 Reading ********* -- procedure: tar:open-archived-file (tar:open-archived-file [PORT]) Reads the next header-record from `PORT' (which defaults to the value of `(current-input-port)') and returns two values: an input-port representing the contents of the next file in the archive and a tar-header record. If no more files are stored in the archive, then `#!eof' and `#f' is returned.  File: tar.egg.info, Node: Writing, Next: Accessing header records, Prev: Reading, Up: Top 4 Writing ********* -- procedure: tar:write-to-archive (tar:write-to-archive FILENAME STRING [PORT #!key mode uid gid modification-time type-flag link-name uname gname devmajor devminor]) Writes the data given in `STRING' as `FILENAME' to the archive designated by the output port `PORT' (which defaults to the value of `(current-output-port)'). The keyword arguments specify additional information in the header-record for this file, see the table below for the default used when no arguments are given: `mode' `(bitwise-ior Permissions perm/irusr perm/iwusr perm/irgrp perm/gwgrp perm/iwoth perm/iwoth)' `uid' `(current-user-id)' Numeric user-id of the file owner `gid' `(current-group-id)' Numeric group-id of the file owners `modification-time' `(current-seconds)' Modification-time of the file when it was archived as the number of seconds from Jan.1, 1970 UTC `type-flag' `'normal' One of symbols `normal, oldnormal, link, symlink, chr, blk, dir, fifo, contig' `link-name' `""' Name of a hard or symbolic link `uname' `(car Username of the (user-information file owner uid))' `gname' `(car Groupname of the (group-information file owners gid))' `devmajor' `0' Major device number of device-files of type `blk' or `chr' `devminor' `0' Minor device number of device-files of type `blk' or `chr' After the last file, a termination record should be written to the port that represents the archive (invoke `tar:write-to-archive' with `#f' as the `FILENAME' argument).

X) Returns `#t' when `X' is a header-record or `#f' otherwise. -- procedure: tar:header-name (tar:header-name HEADER) -- procedure: tar:header-mode (tar:header-mode HEADER) -- procedure: tar:header-size (tar:header-size HEADER) -- procedure: tar:header-uid (tar:header-uid HEADER) -- procedure: tar:header-gid (tar:header-gid HEADER) -- procedure: tar:header-modification-time (tar:header-modification-time HEADER) -- procedure: tar:header-checksum (tar:header-checksum HEADER) -- procedure: tar:header-type-flag (tar:header-type-flag HEADER) -- procedure: tar:header-link-name (tar:header-link-name HEADER) -- procedure: tar:header-magic (tar:header-magic HEADER) -- procedure: tar:header-uname (tar:header-uname HEADER) -- procedure: tar:header-gname (tar:header-gname HEADER) -- procedure: tar:header-devmajor (tar:header-devmajor HEADER) -- procedure: tar:header-devminor (tar:header-devminor HEADER) Accessors for various fields of a tar header record.
