我想复制带偏移的内存块,是否可能？
这是我到目前为止的代码：
const
SOURCE: array [0..5] of Byte = ($47,$49,$46,$38,$39,$61);
var
Destination: Pointer;
begin
// This is a full copy
Move(SOURCE,Destination^,SizeOf(SOURCE));
// If i want to copy from the third byte,is it possible?
// I imagine the code should be,but it cannot be compiled.
Move(Slice(SOURCE^,{Offset=}2)^,SizeOf(SOURCE) - 2);
end;
解决方法
你想要实现的目标并不完全清楚,但它看起来像
MoveMemory(pointer(NativeUInt(Destination) + 2),@SOURCE[0],SizeOf(SOURCE) - 2)
虽然我怀疑你真的想要
MoveMemory(pointer(NativeUInt(Destination) + 2),@SOURCE[2],SizeOf(SOURCE) - 2)
