GetHandleCreatorThreadId Method

Retrieves the Id of the thread that opened the specified file handle.

Syntax

cbfs.getHandleCreatorThreadId(handleInfo, [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 certain events to retrieve the Id of the thread that opened the file handle specified by HandleInfo. The value to pass for HandleInfo should be obtained directly from the event. If the query fails, this method returns 0.

Please note that thread Ids are not unique, and may be reused by different threads over time.

Note: This method can only be called within events that expose a HandleInfo parameter, and must be called in the same thread that the event was originally fired on.
