UrgentData Property

A string of data to be sent urgently (out-of-band) to the remote host.

Syntax


 telnet.setUrgentData( urgentData_Buffer, [callback])

Default Value

""


Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getUrgentData([callback]) method is defined as:

function(err, buffer){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'buffer' is the value returned by the method.

The callback for the setUrgentData([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

The UrgentData property behaves exactly like the DataToSend property except that the data is sent Out Of Band (urgent). This means that the data assigned to UrgentData will bypass the normal TCP queuing mechanism. Use this property with caution.

This property is write-only and not available at design time.

Data Type

Buffer
