VOID NdisMoveMappedMemory( OUT PVOID Destination , IN PVOID Source , IN ULONG Length );
Parameters
- Destination
- Specifies the base virtual address within the mapped range at which the data should be copied.
- Source
- Specifies the base virtual address within the mapped range at which the copy should begin.
- Length
- Specifies the number of bytes to copy.
Remarks
Both the Sourceand Destinationpointers are virtual addresses. The virtual ranges specified both by Destinationand Lengthand by Sourceand Lengthmust fall within the range that was mapped during initialization with NdisMMapIoSpace.
A driver that calls this function can run at any IRQL.
