As DJGPP was a DOS compiler, all games which used Allegro therefore used DOS.

DJGPP ( DJ's GNU Programming Platform ) is a development suite for 386-based IBM PC compatibles which supports DOS-compatible operating systems.

Student Florian Paul Klämpfl started developing his own compiler, written in the Turbo Pascal dialect, and produced 32-bit code for the go32v1 extender, which was used and developed by the DJGPP project at that time.

A port for DOS using DJGPP is also available.

Because the x86-64 versions of Windows lack support for 16-bit programs, there is no NTVDM, and DJGPP apps cannot be run.

PMODE / DJ is a DOS extender derived from PMODE 3. 07 by Matthias Grimrath for use with the DJGPP compilers.

It has been ported to Microsoft Windows and distributed with Cygwin and MinGW, to DOS by the DJGPP project, to Novell NetWare and to Android via various terminal emulation applications.

The original Quake for DOS was compiled with DJGPP, as well as other programs such as GNU Emacs, p7zip, Vim, beye, UPX, NASM, THE, Linley's Dungeon Crawl, NetHack, Perl, Python, and auxiliary applications within Arachne.

Common examples are the MKS Toolkit ( sh, bash, ksh, csh, tclsh, rsh with version 8. 0 and subsequent ), UnxUtils, UWIN ( AT & T Unix for Windows, also abbreviated U / WIN ), Cygwin, DJGPP, Interix, and other programmes of the same type.

However, Shawn abandoned the Atari version as he realized the platform was dying, and reimplemented his work for the Borland C ++ and DJGPP compilers in 1995.

Support for Borland C ++ was dropped in version 2. 0, and DJGPP was the only supported compiler.

The current version of Allegro supports Unix ( Linux, FreeBSD, Irix, Solaris, Darwin ), Windows ( MSVC, MinGW, Cygwin, Borland C ++), Mac OS X and, up to the 4. 2 version, BeOS, QNX, and DOS ( DJGPP, Watcom ).

While DJGPP runs in 32-bit protected mode, its stub and library heavily rely upon many 16-bit DOS and BIOS calls.

* DOS using DJGPP: PythonD

* DJGPP – partially POSIX compliant

* DJGPP FAQ part 4 briefly lists some pros and cons of PMODE / DJ compared to CWSDPMI.

The device's physical characteristics are mediated by the operating system which in turn presents an abstract interface that allows the programmer to read and write bytes from / to the device.

Unlike SPMD, shared memory multiprocessing, also called symmetric multiprocessing or SMP, presents the programmer with a common memory space and the possibility to parallelize execution by having the program take different paths on different processors.

A Device Register is the view any device presents to a programmer.

The human editor / programmer creates the search and visualization function and the machine then collects, edits, and presents text and images according to criteria built into the program.

The LLC sublayer presents a uniform interface to the user of the data link service, usually the network layer.

The philosophy of probability presents problems chiefly in matters of epistemology and the uneasy interface between mathematical concepts and ordinary language as it is used by non-mathematicians.

This presents many advantages as mod authors do not need to worry about crashing the entire game with bad code, clients could show more advanced effects and game menus than was possible in Quake II and the user interface for mods was entirely customizable.

Simple DirectMedia Layer ( SDL ) is a cross-platform, free and open source multimedia library written in C that presents a simple interface to various platforms ' graphics, sound, and input devices.

Ubiquitous computing presents challenges across computer science: in systems design and engineering, in systems modelling, and in user interface design.

* A human – machine interface or HMI is the apparatus or device which presents process data to a human operator, and through this, the human operator monitors and controls the process.

A human – machine interface or HMI is the apparatus which presents process data to a human operator, and through which the human operator controls the process.

Besides the sound device drivers, ALSA bundles a user space library for application developers who want to use driver features through an interface that is higher level than the interface provided for direct interaction with the kernel drivers ; unlike the kernel API, which tries to reflect the capabilities of the hardware directly, ALSA's user space library presents an abstraction which remains as standardized as possible across disparate underlying hardware.

In February 2010, the social-networking site Facebook opened up its chat feature to third-party applications via XMPP. The Facebook developers ' site notes that Facebook Chat does not actually run an XMPP server internally, but merely presents an XMPP interface to clients ; consequently, some server-side features like roster editing cannot be done via XMPP.

The Tor onion proxy software presents a SOCKS interface to its clients.

By default, however, Sam presents its own graphical user interface ( GUI ) window, samterm, which additionally allows point-and-click operations through Smalltalk-80-style pop-up context menus.

A computer using a graphical user interface presents menus with a combination of text and symbols to represent choices.

It is also the component of the operating system that presents many user interface items on the monitor such as the taskbar and desktop.

A graphical interface that presents price, volume and technical analysis indicators through a variety of visual interfaces such as line, bar, candlestick and open-high-low-close ( OHLC ) charts.

It abstracts the values from the GConf database and presents them in an interface similar to Microsoft Windows ' registry editor.

A software wizard or setup assistant is a user interface type that presents a user with a sequence of dialog boxes that lead the user through a series of well-defined steps.

If a service presents a simple interface that abstracts away its underlying complexity, users can access independent services without knowledge of the service's platform implementation.

This approach provides the maximum immersion, but presents complexity with interface electronics and driver software needing to be fabricated.

Implementing these connection interfaces within the computer presents similar challenges to the networking interfaces ( indeed iSCSI runs over the network interface ), and similarly these can be removed from the blade and presented individually or aggregated either on the chassis or through other blades.

The BeIA system presents a browser based interface to the user.

** Tiger Cache Cleaner is shareware software which installs and presents a graphic interface for using ClamAV to scan for viruses, and provides other unrelated functions.

It presents a COM interface for accessing and editing web pages in any COM-supported environment, like C ++ and. NET.
