readline.moveCursor(stream, dx, dy[, callback])

readline.moveCursor() 方法相对于它在给定的 TTY stream 中的当前位置移动光标。

  • stream <stream.Writable>
  • dx <number>
  • dy <number>
  • callback <Function> Invoked once the operation completes.
  • Returns: <boolean> false if stream wishes for the calling code to wait for the 'drain' event to be emitted before continuing to write additional data; otherwise true.

The readline.moveCursor() method moves the cursor relative to its current position in a given TTY stream.
