Timeout Property
This property contains a timeout for the component.
Syntax
ipdaemon.getTimeout(index, [callback]) ipdaemon.setTimeout(index, timeout, [callback])
Default Value
0
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 getTimeout([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setTimeout([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
This property contains a timeout for the class.
If the Timeout property is set to 0, all operations return immediately, potentially failing with a 'WOULDBLOCK' error if data can't be sent or received immediately.
If Timeout is set to a positive value, the class will automatically retry each operation that would otherwise result in a 'WOULDBLOCK' error for a maximum of Timeout seconds.
The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete, the class fails with an error.
Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
Optionally, the behavior of the class may be changed to absolute timeouts, i.e. the class will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.
This behavior is controlled by the AbsoluteTimeout configuration setting.
The default value for the Timeout property is 0 (asynchronous operation).
The size of the array is controlled by the ConnectionCount property.
This property is not available at design time.
