/***
*rmtmp.c - remove temporary files created by tmpfile.
*
* Copyright (c) 1985-1995, Microsoft Corporation. All rights reserved.
*
*Purpose:
*
*Revision History:
* 09-15-83 TC initial version
* 11-02-87 JCR Multi-thread support
* 12-11-87 JCR Added "_LOAD_DS" to declaration
* 05-27-88 PHG Merged normal and DLL versions
* 06-10-88 JCR Use near pointer to reference _iob[] entries
* 08-18-89 GJF Clean up, now specific to OS/2 2.0 (i.e., 386 flat
* model). Also fixed copyright and indents.
* 02-15-90 GJF Fixed copyright
* 03-19-90 GJF Made calling type _CALLTYPE1, added #include
* <cruntime.h> and removed #include <register.h>.
* 10-03-90 GJF New-style function declarator.
* 01-21-91 GJF ANSI naming.
* 07-30-91 GJF Added support for termination scheme used on
* non-Cruiser targets [_WIN32_].
* 03-11-92 GJF Replaced _tmpnum(stream) with stream->_tmpfname for
* Win32.
* 03-17-92 GJF Got rid of definition of _tmpoff.
* 03-31-92 GJF Merged with Stevesa's changes.
* 04-16-92 GJF Merged with Darekm's changes.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 10-29-93 GJF Define entry for termination section (used to be in
* i386\cinittmp.asm). Also, replaced MTHREAD with _MT
* and deleted old Cruiser support.
* 04-04-94 GJF #ifdef-ed out definition _tmpoff for msvcrt*.dll, it
* is unnecessary. Made definitions of _tempoff and
* _old_pfxlen conditional on ndef DLL_FOR_WIN32S.
* 02-20-95 GJF Merged in Mac version.
* 03-07-95 GJF Converted to walk the __piob[] table (rather than
* the _iob[] table).
* 03-16-95 GJF Must be sure __piob[i]!=NULL before trying to lock it!
* 03-28-95 SKS Fix declaration of _prmtmp (__cdecl goes BEFORE the *)
