A KeQuerySystemTime alternate function under x64 ?
in [Device Drivers]

From: GeminiServer on 8 Dec 2009 09:01 Hi, i have a problem that there is no KeQuerySystemTime for x64. I need the system time also under x64. (not IA64). Can some tell me a way or a an alternate function under x64 to get the system time. cheers, GeminiServer
From: Don Burn on 8 Dec 2009 09:12 Why do you think that the call is not there? It is a macro, but certainly present. -- Don Burn (MVP, Windows DKD) Windows Filesystem and Driver Consulting Website: http://www.windrvr.com Blog: http://msmvps.com/blogs/WinDrvr Remove StopSpam to reply "GeminiServer" <melih_ataoglu(a)hotmail.com> wrote in message news:%23KFwu7AeKHA.1596(a)TK2MSFTNGP06.phx.gbl... > Hi, > > i have a problem that there is no KeQuerySystemTime for x64. > I need the system time also under x64.

Then i did a seachr in the WDK, there was no KeQuerySystemTime explizit for x64. I only found for 386 & IA64. Then i found the definition for x64 and include it to my x64 source. Which will compile without problems. But this is for IA64 right? --> 0xFFFFF78000000000UI64 ....UI64 ? A fixed tickcount adress ?

From: Don Burn on 8 Dec 2009 11:09 So are you trying to get the function address or just trying to use the function? If you want the function address you are out of luck. The macro works fine and no 0xFFFFF78000000000UI64 means a constant that is an Unsigned Integer 64-bits not something that works only on Itanic (i.e. IA64). -- Don Burn (MVP, Windows DKD) Windows Filesystem and Driver Consulting Website: http://www.windrvr.com Blog: http://msmvps.com/blogs/WinDrvr Remove StopSpam to reply "GeminiServer" <melih_ataoglu(a)hotmail.com> wrote in message news:uiDEj9BeKHA.4880(a)TK2MSFTNGP05.phx.gbl... > Don Burn schrieb: >> Why do you think that the call is not there?
