# Node location atom structure ('nloc')

An atom that describes the type of a node and its location.

## Overview

Overview The node location atom is the only child atom defined for the node ID atom. Its atom type is kQTVRNodeLocationAtomType ('nloc'). A node location atom describes the type of a node and its location. The structure of a node location atom is defined by the QTVRNodeLocationAtom data type: typedef struct VRNodeLocationAtom {     UInt16                              majorVersion;     UInt16                              minorVersion;     OSType                              nodeType;     UInt32                              locationFlags;     UInt32                              locationData;     UInt32                              reserved1;     UInt32                              reserved2; } VRNodeLocationAtom, *QTVRNodeLocationAtomPtr; QT QT
