WaitForChanges Method

This method waits for changes to a folder for a specified period of time.

Syntax

dropbox.waitForChanges(timeout, [callback])

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 this 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.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method waits for changes to be made to a folder for Timeout seconds.

This method returns True if changes were made and False if no changes were made. The method may return before Timeout expires if a change is made.

Valid values for Timeout are between 30 and 480.

Note: Dropbox may add up to 90 seconds of jitter to the connection, as a result the Timeout parameter may not strictly define the time to wait.
