✖
DeviceStreams[device]

gives a list of all open streams associated with a device.

✖
DeviceStreams[device,patt]

gives a list of streams whose names match the string pattern patt.

✖
DeviceStreams[device,{patt1,patt2,…}]

gives a list of streams whose names match any of the patti.

Details

  • A device can be specified either by a DeviceObject or by a string representing a device class.
  • Streams are automatically opened when a device is opened and are closed when it is closed.
  • DeviceStreams can return InputStream or OutputStream objects.

Examples
