From: Maxim on 17 Dec 2007 17:03 I am trying to allocate memory in a STORPORT miniport driver via StorPortAllocatePool. I am suing WDK6000. The function is defined in storport.h as a wrapper around StorPortExtendedFunction. At compile time, I get: error LNK2019: unresolved external symbol __imp__StorPortExtendedFunction referenced in function _StorPortAllocatePool(a)16 objchk_wnet_x86\i386\vtms_stor.sys : fatal error LNK1120: 1 unresolved externals I also saw on MSDN that AllocatePool could be referenced via a pointer from STORPORT_EXTENDED_FUNCTIONS structure which could be retrieved by calling StorPortNotification with GetExtendedFunctionsTable and a pointer to a pointer to this structure. If I do that, the pointer stays as NULL. Whats going on?

From: Maxim on 18 Dec 2007 18:19 I see. Any idea how I can allocate memory in a StorPort miniport driver prior to Vista? "Andrew Sha" wrote: > AFAIK, this API is for Vista only, not sure about WS03SP2
