VideoPortMoveMemory

VOID VideoPortMoveMemory(

PVOID Destination,

PVOID Source,

ULONG Length

);

VideoPortMoveMemory copies data from the source location to the destination location in system memory.

Parameters

Destination: Points to the destination location.
Source: Points to the location of the data to copy.
Length: Specifies the number of bytes to copy.

Comments

VideoPortMoveMemory moves memory either forward or backward, aligned or unaligned, in 4-byte blocks, followed by any remaining bytes.

The given Destination and Source must be in a mapped logical range returned by VideoPortGetDeviceBase and/or a system-space RAM address, such as an address on the stack. Attempting to transfer data to or from a device-memory block, such as an adapter frame buffer or ROM block, can cause access violations in certain Windows NT® RISC-based platforms.
