事件:'SIGTSTP'


¥Event: 'SIGTSTP'

input 流接收到 Ctrl+Z 输入(通常称为 SIGTSTP)时,会触发 'SIGTSTP' 事件。如果 input 流接收到 SIGTSTP 时没有注册 'SIGTSTP' 事件监听器,则 Node.js 进程将被发送到后台。

¥The 'SIGTSTP' event is emitted when the input stream receives a Ctrl+Z input, typically known as SIGTSTP. If there are no 'SIGTSTP' event listeners registered when the input stream receives a SIGTSTP, the Node.js process will be sent to the background.

当使用 fg(1p) 恢复程序时,则将触发 'pause''SIGCONT' 事件。这些可用于恢复 input 流。

¥When the program is resumed using fg(1p), the 'pause' and 'SIGCONT' events will be emitted. These can be used to resume the input stream.

如果 input 在进程发送到后台之前暂停,则不会触发 'pause''SIGCONT' 事件。

¥The 'pause' and 'SIGCONT' events will not be emitted if the input was paused before the process was sent to the background.

调用监听器函数时不传入任何参数。

¥The listener function is invoked without passing any arguments.

rl.on('SIGTSTP', () => {
  // This will override SIGTSTP and prevent the program from going to the
  // background.
  console.log('Caught SIGTSTP.');
}); 

Windows 不支持 'SIGTSTP' 事件。

¥The 'SIGTSTP' event is not supported on Windows.
