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.

// Each individual file that calls bugcheck needs to have defined at the

// FAT_BUG_CHECK_ values defined below and then use FatBugCheck to bugcheck
