VOID VDDSimulate16( )
VDDSimulate16 is similar to VDDSimulateInterrupt except that it does not require a hardware interrupt to be supported by the 16-bit stub device driver. VDDSimulate16 allows a VDD to execute a routine in its 16-bit driver and return when it has finished. Before calling VDDSimulate16, a VDD should preserve at least CS and IP, as well as any other 16-bit registers which its 16-bit routine might destroy. This simulation is synchronous.
