/***
*heapdump.c -  Output the heap data bases
*
*       Copyright (c) 1989-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       Display the heap data bases.
*
*       NOTE:  This module is NOT released with the C libs.  It is for
*       debugging purposes only.
*
*Revision History:
*       06-28-89  JCR   Module created.
*       07-18-89  JCR   Added _heap_print_regions() routine
*       11-13-89  GJF   Added MTHREAD support, also fixed copyright
*       12-13-89  GJF   Changed name of include file to heap.h
*       12-19-89  GJF   Removed references to plastdesc
*       03-11-90  GJF   Made the calling type _CALLTYPE1 and added #include
*                       <cruntime.h>.
*       04-06-93  SKS   Replace _CRTAPI* with __cdecl
*       09-06-94  CFW   Replace MTHREAD with _MT.
*       02-14-95  GJF   Appended Mac version of source file (somewhat cleaned
*                       up), with appropriate #ifdef-s.
*       04-30-95  GJF   Made conditional on WINHEAP.
*       05-17-99  PML   Remove all Macintosh support.
