This function copies data from a system-space buffer to device memory that was mapped during initialization with the NdisMMapIoSpacefunction.
VOID NdisMoveToMappedMemory( OUT PVOID Destination , IN PVOID Source , IN ULONG Length );
An NIC driver calls this function to copy data from a buffer in the host to mapped device memory, as, for example, when transferring data from a protocol-supplied buffer or miniport-allocated staging buffer to the NIC for a transmit.
Both the Sourceand Destinationpointers are virtual addresses. The virtual range specified by Destinationand Lengthmust fall within a range that was mapped with the NdisMMapIoSpacefunction.
A driver that calls this function can run at any IRQL when the given Sourceand Destinationare resident. Otherwise, callers must be running at IRQL < DISPATCH_LEVEL, as, for example if the Sourceaddress is on the stack.
