gzip is a file format and a software application used for file compression and decompression.The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from which the "g" of gzip is derived).
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
Software distributors use executable compression for a variety of reasons, primarily to reduce the secondary storage requirements of their software; as executable compressors are specifically designed to compress executable code, they often achieve better compression ratio than standard data compression facilities such as gzip, zip or bzip2 [citation needed].
libzip is an open-source library for handling zip archives. It is written in portable C and can thus be used on multiple operating systems. It is based on zlib.It is used by PHP's zip extension for zip file support [2] and MySQL Workbench. [3]
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
Traditionally, when creating a bootable kernel image, the kernel is also compressed using gzip, or, since Linux 2.6.30, [3] using LZMA or bzip2, which requires a very small decompression stub to be included in the resulting image. The stub decompresses the kernel code, on some systems printing dots to the console to indicate progress, and then ...
zlib (/ ˈ z iː l ɪ b / or "zeta-lib", / ˈ z iː t ə ˌ l ɪ b /) [2] [3] is a software library used for data compression as well as a data format. [4] zlib was written by Jean-loup Gailly and Mark Adler and is an abstraction of the DEFLATE compression algorithm used in their gzip file compression program. zlib is also a crucial component of many software platforms, including Linux, macOS ...
The file that is produced by lzip is usually given .lz as its filename extension, and the data is described by the media type application/lzip. The lzip suite of programs was written in C++ and C by Antonio Diaz Diaz and is being distributed as free software under the terms of version 2 or later of the GNU General Public License (GPL).
