RtlCopyMemory

VOID
    RtlCopyMemory(
        IN VOID UNALIGNED  *Destination,
        IN CONST VOID UNALIGNED  *Source,
        IN ULONG  Length
        );

RtlCopyMemory copies the contents of one buffer to another.

Parameters

Destination

Points to the destination of the move.

Source

Points to the memory to be copied.

Length

Specifies the number of bytes to be copied.

Comments

RtlCopyMemory runs faster than RtlMoveMemory. However, the (Source + Length) cannot overlap the Destination range passed in to RtlCopyMemory.

Callers of RtlCopyMemory can be running at any IRQL if both memory blocks are resident. Otherwise, the caller must be running at IRQL < DISPATCH_LEVEL.
