NdisMoveMappedMemory

  • Article

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

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

Parameters

  • Source
    Specifies the base virtual address within the mapped range at which the copy should begin.
  • Length

Remarks

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.

A driver that calls this function can run at any IRQL.
