Ruby Interrupt類用法及代碼示例

在收到中斷信號時引發，通常是因為用戶按下了Control-C(在大多數 posix 平台上)。因此，它是 SignalException 的子類。

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

產生：

Press ctrl-C when you get bored

then waits until it is interrupted with Control-C and then prints:

Note: You will typically use Signal.trap instead.
