Cygwin Documentation * Cygwin User's Guide * Cygwin API Reference * Frequently Asked Questions (FAQ) file for Cygwin. Some work remains to be done in documenting the Cygwin API. In addition to the Cygwin API Reference and information in the FAQ, you may want to check source code file winsup/cygwin.din which lists all of the Cygwin DLL exports. We have some preliminary docs on how to profile the Cygwin DLL. Information on building and using DLLs is here. Also note that there is quite a lot of useful information in the project mailing list archives.

Cygwin Information and Installation

by 11 others (via)
What Is Cygwin? # Cygwin is a Linux-like environment for Windows. It consists of two parts: A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality. # A collection of tools which provide Linux look and feel. The Cygwin DLL currently works with all recent, commercially released x86 32 bit and 64 bit versions of Windows, with the exception of Windows CE. Note that the official support for Windows 95, Windows 98, and Windows Me will be discontinued with the next major version (1.7.0) of Cygwin. What Isn't Cygwin? # Cygwin is not a way to run native linux apps on Windows. You have to rebuild your application from source if you want it to run on Windows. # Cygwin is not a way to magically make native Windows apps aware of UNIX ® functionality, like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality.

VirtualBox - VirtualBox

by 2 others
VirtualBox -- professional, flexible, open ¶ innotek VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. Some of the features of VirtualBox are: * Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox. * Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers. * Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window). A number of extra features are available with the full VirtualBox release only (see the "Editions" page for details): * Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host. * Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data. * USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in. * Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines. Versions ¶ VirtualBox comes in different versions, depending on your needs. Please see the Editions page for details. Screenshots ¶ We have put together a small tour of the VirtualBox features on the Screenshots page. Press Coverage ¶ We maintain a link list to press articles about VirtualBox on the Press page.
