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

  61 //  (in the high word) and the line number of the bugcheck (in the low word).

  63 //  necessary.

  67 //  CDFS_BUG_CHECK_ values defined below and then use CdBugCheck to bugcheck
  68 //  the system.
