Copies the current topmost value on the evaluation stack, and then pushes the copy onto the evaluation stack.
复制计算堆栈上当前最顶端的值,然后将副本推送到计算堆栈上。
If we are assigning one value variable to the other variable, it creates two distinct copies of the same data on the stack. So now in the stack there are two Spaces allocated.
如果我们将一个变量赋值给另外一个变量,在堆栈中则会创建两个不同的复本,尽管它们的数据是一样的,因此,在堆栈中分配了两块空间。
This warning indicates that a parameter that points to a non-stack buffer of known size is being passed into a function that copies more bytes into it than that size.
此警告意味着,正将指向已知大小的非堆栈缓冲区的参数传递到某个函数,但是该函数向缓冲区中复制的字节数大于缓冲区的大小。
