没怎么用过,这是帮助:function Ptr(Address: Integer): Pointer;Ptr converts the given address to a pointer. A call to this function generates no code, but simply treats the 32-bit value given by Address as a pointer. Like nil, the result of Ptr is assignment compatible with all pointer types.
ptr 将给点地址转换为一个指针。A 调用这个函数不产生任何代码,但是简单地将给定地址作为一个32位值赋给一个指针。如为空,Ptr的返回结果值将分配所有指针类型。
