|
*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
