ZZIPlib

ZZIPlib library is intentionally lightweight, it offers the ability to easily extract data from files archived in a single zip file. Applications can bundle files into a single zip archive and access them. The implementation is based only on the (free) subset of compression with the zlib algorithm which is actually used by the zip/unzip tools.

The library allows reading zip archives in a number of ways,

archive mode:

reading the zip directory and extracting files from it. This is the traditional mode as seen with unzip-utilities. Some extra unzip-utiles for transparent/magic mode are shipped as well.

replacement mode:

Use ZZIP_FILE / ZZIP_DIR pointers provided by zziplib and put them to work with routines originally developped to work with real directories and file handles. The API calls do follow traditional synopsis from posix/stdio.

transparent mode:

Use replacement handles and allow the open()-calls to automatically detect when a file is contained in a zip archive or when it is a real file in the file system. A filepath can be partly in a real filesystem and partly within the zip archive when one is seen.

ext magic

Use the same filepath to access either a zipped or real file - it looks for a real file and there is none then every subdirectory of the path is checked, a ".zip" extension appended, and the zipped file transparently opened. This can speed up dat-file development dramatically.

io/xor magic

The access to the filesystem can be hooked up - examples are given for xor obfuscation which is great for game artwork and AI data. A small intro for SDLrwops usage is given as well.

What is new in this release:

• This version contains build fixes for Linux, AIX, mingw32, and MSVC8.
• Bugfixes include that stat-caseless was not working and a segfault for very large (non-standard) zip32 archives.

What is new in version 0.13.56:

• Fixed some bugs, added modulo-entries feature, changed package scheme for manpages, and updated configure scheme for better build portability.

What is new in version 0.13.53:

• Fixed the sdl example and redone its packaging. Also the zzip-postinstall symlinks were fixed as well as some minor beauty cleanups were done. The libzzip core should be working identical.
• Note that the default rpm spec will now run "make check" and "make test-sdl" before actually performing the installation. During testing the "make docs" has shown to be flaky in that it does sometimes break barking at errors in the docbook dtd - but I guess that is a suse-specific tooling problem and most people will not run xmlto + docbook-xsl anyway.

Requirements:

• zlib
