AsString – memcpy()

Copies the memory area

nxt_adr = memcpy(adr(Dest),adr(Src),length)

I/O	Parameter	Data type	Description
IN	pDest	ANY (transferred as a pointer)	Address of destination memory
IN	pSrc	ANY (transferred as a pointer)	Address of data to be copied
IN	length	UDINT	Number of bytes to be copied
OUT	nxt_adr	UDINT	Address of the byte following the copied data in the destination memory
