Examples of org.lwjgl.openal.ALCdevice

org.lwjgl.openal.ALCdevice
The ALCdevice class represents a device opened in OpenAL space. ALC introduces the notion of a Device. A Device can be, depending on the implementation, a hardware device, or a daemon/OS service/actual server. This mechanism also permits different drivers (and hardware) to coexist within the same system, as well as allowing several applications to share system resources for audio, including a single hardware output device. The details are left to the implementation, which has to map the available backends to unique device specifiers. @author Brian Matzon @version $Revision: 3418 $$Id: ALCdevice.java 3418 2010-09-28 21:11:35Z spasi $
