GetVolumeGUID Method

Retrieves the volume GUID of the device targeted by a filesystem operation.

Syntax

cbmonitor.getVolumeGUID([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 can be called within events fired for filesystem operations to retrieve the volume GUID of the device targeted by the operation, returned in the Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} format. If the query fails, this method returns empty string.

Volume GUIDs can be used to enumerate the mounting points of a device using the Windows API's GetVolumePathNamesForVolumeName function.

Note: This method can only be called within events.
