From: muriwai on 27 Apr 2008 05:57 Hi, I have MyDriver.sys that can be loaded on Server 2003 and 2008. The driver imports a function from ksecdd.sys. The function is available on 2008 only. How do I dynamically link to ksecdd.sys? MmGetSystemRoutineAddress doesn't work. Can I use delayed imports in a kernel mode driver? Thank you, Andrew

From: muriwai on 28 Apr 2008 21:57 Thanks Doron. How do I make sure ksecdd won't be unloaded in the middle?

From: muriwai on 29 Apr 2008 06:01 Never mind, I'll statically link to a function that present in both 2005 and 2008....

exactly. if you staticly link against ksecdd, it will not unload as long as our driver is loaded. d -- Please do not send e-mail directly to this alias. this alias is for newsgroup purposes only.
