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 Lengthbytes 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 Lengthbytes in size.
- Length
- Specifies the number of bytes to copy.
Remarks
Both Sourceand Destinationare virtual addresses.
If either address falls within a range of device memory that was mapped with the NdisMMapIoSpacefunction, an NIC driver calls one of the Ndis XXXMappedMemoryfunctions instead of this function.
The range specified by Sourceand Lengthcannot overlap the Destinationrange.
A driver that calls this function can run at any IRQL if the given Sourceand Destinationare 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.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 2.0 and later Ndis.h Note This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
