*userapi.cpp - RTC support
*
* Copyright (c) 1998-2001, Microsoft Corporation. All rights reserved.
*
*
*Revision History:
* 07-28-98 JWM Module incorporated into CRTs (from KFrei)
* 07-30-98 JWM errnum is now type _RTC_ErrorNumber throughout.
* 10-09-98 KBF moved _RTC_IsEnabled to init.cpp (it now works for
* EXE/DLL combos)
* 05-11-99 KBF Error if RTC support define not enabled
* 05-26-99 KBF Updated for -RTCu, -RTClv cancelled
