Function Documentation

CopyMem()

VOID *EFIAPI CopyMem	(	OUT VOID *	DestinationBuffer,
		IN CONST VOID *	SourceBuffer,
		IN UINTN	Length
	)

Copies a source buffer to a destination buffer, and returns the destination buffer.

This function copies Length bytes from SourceBuffer to DestinationBuffer, and returns DestinationBuffer. The implementation must be reentrant, and it must handle the case where SourceBuffer overlaps DestinationBuffer.

If Length is greater than (MAX_ADDRESS - DestinationBuffer + 1), then ASSERT(). If Length is greater than (MAX_ADDRESS - SourceBuffer + 1), then ASSERT().

Parameters

DestinationBuffer	The pointer to the destination buffer of the memory copy.
SourceBuffer	The pointer to the source buffer of the memory copy.
Length	The number of bytes to copy from SourceBuffer to DestinationBuffer.

Returns

DestinationBuffer.
