Yes, unless there is an embedded callback pointer in the structure PCI_INFO, you'll be able to call the DLL (it appears to be a C-style DLL from the statement above.) You'll likely need to use something like Christof Lange's STRUCT or my CLSHeap classes to handle the data structure if there's any indirection; both can be downloaded from the Files Section.
