Module Name:

    NodeType.h

Abstract:

    This module defines all of the node type codes used in this development
    shell.  Every major data structure in the file system is assigned a node
    type code that is.  This code is the first CSHORT in the structure and is
    followed by a CSHORT containing the size, in bytes, of the structure.
