中断类
当接收到中断信号时引发,通常是因为用户按下了 Control-C(在大多数 posix 平台上)。因此,它是 SignalException
的子类。
begin puts "Press ctrl-C when you get bored" loop {} rescue Interrupt => e puts "Note: You will typically use Signal.trap instead." end
产生
Press ctrl-C when you get bored
然后等待直到它被 Control-C 中断,然后打印
Note: You will typically use Signal.trap instead.
