NdisMoveMappedMemory

VOID
   NdisMoveMappedMemory(
       OUT PVOID Destination,
       IN PVOID Source,
       IN ULONG Length
       );

NdisMoveMappedMemory copies data from one location to another within a device memory range that was mapped during initialization with NdisMMapIoSpace.

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.

Comments

Both the Source and Destination pointers are virtual addresses. The virtual ranges specified both by Destination and Length and by Source and Length must fall within the range that was mapped during initialization with NdisMMapIoSpace.

Callers of NdisMoveMappedMemory can run at any IRQL.
