GetHandleCreatorProcessId Method

Retrieves the Id of the process (PID) that opened the file handle.

Syntax

public int getHandleCreatorProcessId();

Remarks

This method can be called within certain events to retrieve the Id of the process (PID) that opened the file handle. If the query fails, this method returns 0.

Please note that PIDs are not unique, and may be reused by different processes over time (though in practice, this is uncommon).

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:

  1. Call this method within the AfterCreateFile or AfterOpenFile event.
  2. Store the information somewhere, and store a reference to it in the event's HandleContext parameter.
  3. In a later event, access the information via the reference stored in HandleContext.
Please refer to the Contexts topic for more information on how to use events' context parameters.
