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.

// The following definitions are used to generate meaningful blue bugcheck

// The other values can be whatever the caller of the bugcheck routine deems
// necessary.

// Each individual file that calls bugcheck needs to have defined at the
// start of the file a constant called BugCheckFileId with one of the
// CDFS_BUG_CHECK_ values defined below and then use CdBugCheck to bugcheck
// the system.
