NdisMoveMemory
This function copies a specified number of bytes from one caller-supplied location to another.
VOID NdisMoveMemory(
OUT PVOID Destination,
IN PVOID Source,
IN ULONG Length );
Parameters
- Destination
Pointer to a system-space buffer that is the destination of the move. This buffer must be at least Length bytes in size. - Source
Pointer to a system-space buffer from which this function copies the data to the destination buffer. This buffer must be at least Length bytes in size. - Length
Specifies the number of bytes to copy.
Remarks
Both Source and Destination are virtual addresses.
If either address falls within a range of device memory that was mapped with the NdisMMapIoSpace function, an NIC driver calls one of the NdisXXXMappedMemory functions instead of this function.
The range specified by Source and Length cannot overlap the Destination range.
A driver that calls this function can run at any IRQL if the given Source and Destination are resident. Otherwise, a driver that calls this function must be running at IRQL < DISPATCH_LEVEL, as, for example if either address is on the stack.
