GetHandleCreatorProcessName Method
Retrieves the name of the process that opened the file handle.
Syntax
cbfilter.getHandleCreatorProcessName([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 name of the process that opened the file handle. If the query fails, this method returns empty string.
Applications cannot use this method to retrieve information about remote processes accessing drives shared on the network. Windows does not provide such information due to the nature of remote access.
Note: This method can only be called within the AfterCreateFile and AfterOpenFile events, and must be called in the same thread that the event was originally fired on. Applications that need the information that this method returns during other events can do the following:
- Call this method within the AfterCreateFile or AfterOpenFile event.
- Store the information somewhere, and store a reference to it in the event's HandleContext parameter.
- In a later event, access the information via the reference stored in HandleContext.
