/***
*tidprint.c - Dislpay thread data
*
* Copyright (c) 1988-1991, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Display the per thread data table.
*
* [NOTE: This module is NOT included in the C runtime libraries but
* is maintained for debugging analysis.]
*
*Revision History:
* 11-17-88 JCR Module created.
* 04-03-89 JCR Added _stackalloc to tid table
* 06-06-89 JCR 386 version
* 06-09-89 JCR 386: Added values to _tiddata struc (for _beginthread)
* 04-09-90 GJF Added #include <cruntime.h>. Made the calling type
* _CALLTYPE1. Also, fixed the copyright.
* 04-10-90 GJF Removed #include <dos.h>.
* 08-16-90 SBM Made _terrno and _tdoserrno int, not unsigned
* 10-08-90 GJF New-style function declarators.
* 10-09-90 GJF Thread ids are of type unsigned long!
* 12-18-90 GJF Use real thread id, not thread id - 1.
* 08-01-91 GJF Adapted for Win32 [_WIN32_].
