Interrupt

Interrupt类

Parent:SignalException

接收到中断信号时触发,通常是因为用户在Control-C上(在大多数POSIX平台上)按下。因此,它是一个子类SignalException

begin puts "Press ctrl-C when you get bored" loop {} rescue Interrupt => e puts "Note: You will typically use Signal.trap instead." end

产生如下结果:

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.
