Cygwin
Cygwin ( ) is a POSIX-compatible programming and runtime environment that runs natively on Microsoft Windows. Under Cygwin, source code designed for Unix-like operating systems may be compiled with minimal modification and executed. The Cygwin installation has a directory layout that is similar to the root file system of Unix-like systems, with familiar directories, such as /bin, /home, /etc, /usr, and /var. Cygwin installs with hundreds of command-line tools and other programs commonly found on a Unix-like system. Additionally, many applications may be installed from a packaging system. The terminal emulator Mintty is the default command-line interface provided to interact with the environment. Cygwin provides native integration of Windows-based applications. Thus it is possible to launch Windows applications from the Cygwin environment, as well as to use Cygwin tools and applications within the Windows operating context. Cygwin consists of two parts: a dynamic-link library ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cygwin/X
Cygwin/X is an implementation of the X Window System that runs under Microsoft Windows. It is part of the Cygwin project, and is installed using Cygwin's standard setup system. Cygwin/X is free software, licensed under the X11 License. Cygwin/X was originally based on XFree86, but switched to the X.Org Server due to XFree86 licensing controversy, owing to concerns over XFree86's new software license not being compatible with the GPL. After a long hiatus following an 8 July 2005 release, the project was revitalised and the developers released a version based on the X.org modular 7.4 release on 12 November 2008 and continue to maintain it. Features There are two ways to run Cygwin/X: In one, an X server runs in a single Microsoft Windows window that serves as the X display, which holds the X root window and all the other X windows in the X session. You use an X window manager to manage the X windows within the display. You can run multiple X servers, each in its own Microso ...

Mintty
mintty is a free and open source terminal emulator for Cygwin, the Unix-like environment for Windows. It features a native Windows user interface and does not require a display server; its terminal emulation is aimed to be compatible with xterm. Mintty is based on the terminal emulation and Windows frontend parts of PuTTY, but improves on them in a number of ways, particularly regarding xterm compatibility. It is written in C. The POSIX API provided by Cygwin is used to communicate with processes running within mintty, while its user interface is implemented using the Windows API. The program icon comes from KDE's Konsole. Towards the end of 2011, mintty became Cygwin's default terminal. Advantages over Cygwin's previous default console include a more flexible user interface and closer adherence to Unix standards and conventions. Since it is not based on the standard Windows console, however, programs written specifically for that do not work correctly in mintty. It is al ...

Cygnus Solutions
Cygnus Solutions, originally Cygnus Support, was founded in 1989 by John Gilmore, Michael Tiemann and David Henkel-Wallace to provide commercial support for free software. Its tagline was: ''Making free software affordable''. For years, employees of Cygnus Solutions were the maintainers of several key GNU software products, including the GNU Debugger and GNU Binutils (which included the GNU Assembler and Linker). It was also a major contributor to the GCC project and drove the change in the project's management from having a single gatekeeper to having an independent committee. Cygnus developed BFD, and used it to help port GNU to many architectures, in a number of cases working under non-disclosure to produce tools used for initial bringup of software for a new chip design. Cygnus was also the original developer of Cygwin, a POSIX layer and the GNU toolkit port to the Microsoft Windows operating system family, and of eCos, an embedded real-time operating system.

C Standard Library
The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. ISO/ IEC (2018). '' ISO/IEC 9899:2018(E): Programming Languages - C §7'' Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library. The C standard library provides macros, type definitions and functions for tasks such as string handling, mathematical computations, input/output processing, memory management, and several other operating system services. Application programming interface Header files The application programming interface (API) of the C standard library is declared in a number of header files. Each header file contains one or more function declarations, data type definitions, and macros. After a long period of stabi ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person u ...

POSIX
The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines both the system- and user-level application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers. Name Originally, the name "POSIX" referred to IEEE Std 1003.1-1988, released in 1988. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. The standards emerged from a project that began in 1984 building on work from related activity in the ''/usr/group'' association. Richard Stallman suggested the name ''POSIX'' (pronounced as ''pahz-icks,'' as in ''positive'', not as ''poh-six'') to the IEEE instead of f ...

Compatibility Layer
In software engineering, a compatibility layer is an interface that allows binaries for a legacy or foreign system to run on a host system. This translates system calls for the foreign system into native system calls for the host system. With some libraries for the foreign system, this will often be sufficient to run foreign binaries on the host system. A hardware compatibility layer consists of tools that allow hardware emulation. Software Examples include: * Wine, which runs some Microsoft Windows binaries on Unix-like systems using a program loader and the Windows API implemented in DLLs * Windows's application compatibility layers to attempt to run poorly written applications or those written for earlier versions of the platform. * Lina, which runs some Linux binaries on Windows, Mac OS X and Unix-like systems with native look and feel. * KernelEX, which runs some Windows 2000/XP programs on Windows 98/Me. * Executor, which runs 68k-based "classic" Mac OS programs in Wind ...

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer ...

GNU General Public License
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end user In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrat ...s the Four Freedoms (Free software), four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms.

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run mult ...

Windows API
The Windows API, informally WinAPI, is Microsoft's core set of application programming interfaces (APIs) available in the Microsoft Windows operating systems. The name Windows API collectively refers to several different platform implementations that are often referred to by their own names (for example, Win32 API); see the versions section. Almost all Windows programs interact with the Windows API. On the Windows NT line of operating systems, a small number (such as programs started early in the Windows startup process) use the Native API. Developer support is available in the form of a software development kit, Microsoft Windows SDK, providing documentation and tools needed to build software based on the Windows API and associated Windows interfaces. The Windows API (Win32) is focused mainly on the programming language C in that its exposed functions and data structures are described in that language in recent versions of its documentation. However, the API may be used by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynamic-link Library
Dynamic-link library (DLL) is Microsoft's implementation of the shared library concept in the Microsoft Windows and OS/2 operating systems. These libraries usually have the file extension DLL, OCX (for libraries containing ActiveX controls), or DRV (for legacy system drivers). The file formats for DLLs are the same as for Windows EXE files – that is, Portable Executable (PE) for 32-bit and 64-bit Windows, and New Executable (NE) for 16-bit Windows. As with EXEs, DLLs can contain code, data, and resources, in any combination. Data files with the same file format as a DLL, but with different file extensions and possibly containing only resource sections, can be called ''resource DLLs''. Examples of such DLLs include ''icon libraries'', sometimes having the extension ICL, and font files, having the extensions FON and FOT. Background The first versions of Microsoft Windows ran programs together in a single address space. Every program was meant to co-operate by yieldi ...
