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.  This code is the first CSHORT in the structure and is followed
    by a CSHORT containing the size, in bytes, of the structure.

    A single structure can fake polymorphism by using a set of node type codes.
    This is what the two FCB types do.

//  The following definitions are used to generate meaningful blue bugcheck
//  screens.  On a bugcheck the file system can output 4 ulongs of useful
//  information.  The first ulong will have encoded in it a source file id
//  (in the high word) and the line number of the bugcheck (in the low word).
//  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
//  UDFS_BUG_CHECK_ values defined below and then use UdfBugCheck to bugcheck
//  the system.
//
//  We also will define the debug trace level masks here.  Set UdfsDebugTraceLevel
//  to include a given filemask to see debug information from that module when
//  compiled with debugging.
//

//
//  Not all of these are actually used in UDFS. Perhaps this list will be
//  optimized when UDFS is functionally complete.
