In this case, you're using a simple if... Else block to see whether any value stored in the state is accessible via the random key.
在本例中，我们用一个简单的if . . .else块来判断在状态中保存的值是否可通过random键访问。
The pointer will have some random value that, with luck, will point into an area of memory that is not available to your program and the kernel will kill your program before it can do any damage.
这个指针会有一个随机值，如果运气好的话，它将会指向一个你程序不可用的内存区域，那么内核将会在它造成什么伤害前干掉你的程序。
