VirtualBox SDK 3.1.2 Build 56127

VirtualBox SDK 3.1.2 Build 56127 is a complete software which contains all the documentation and interface files that are needed to write code that interacts with VirtualBox.

The VirtualBox Main API documentation describes the so-called VirtualBox Main API which comprises all public COM interfaces and components provided by the VirtualBox server and by the VirtualBox client library.

VirtualBox employs a client-server design, meaning that whenever any part of VirtualBox is running -- be it the Qt GUI, the VBoxManage command-line interface or any virtual machine --, a dedicated server process named VBoxSVC runs in the background. This allows multiple processes working with VirtualBox to cooperate without conflicts. These processes communicate to each other using inter-process communication facilities provided by the COM implementation of the host computer.
