Current release:

Libcmpio 0.2.5

  April 14, 2011

What is Libcmpio?
Libcmpio is a general purpose library, which provides an easy way to manipulate data files with variable record length, record compression, transparent volume creation and control and portability among different platforms . It works on many Unix-like platforms. The source code is released under the GNU General Public License Version 2. Code embedded in Libcmpio from other open source projects like zlib and libbzip2 is distributed under their respective licenses.

What language did you use?
Libcmpio is written for APE (ANSI C99/POSIX.1-2001 environment). You may impose the compiling of strict ANSI C89 code by adding the option -DCMP_ANSIC89 to the EXTRADEFS environment variable. Two functions, fcntl (2) and fileno (3), are the only non-ANSI C89 functions used when you define the CMP_ANSIC89 macro.
