Module Name:

      DATAHEAP.h

Abstract:

    Header file for the Windows NT heap Performance counters.

    This file contains definitions to construct the dynamic data
    which is returned by the Configuration Registry.  Data from
    various system API calls is placed into the structures shown
    here.
