# Node location atom structure ('nloc')

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

## 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:

```c
typedef struct VRNodeLocationAtom {
    UInt16                              majorVersion;
    UInt16                              minorVersion;
    OSType                              nodeType;
    UInt32                              locationFlags;
    UInt32                              locationData;
    UInt32                              reserved1;
    UInt32                              reserved2;
} VRNodeLocationAtom, *QTVRNodeLocationAtomPtr;
