Retrieves the security token associated with the process that initiated the operation.
This method can be called within events fired for process and thread operations to retrieve the security token associated with the process that initiated the operation. If the query fails, this method returns INVALID_HANDLE_VALUE.
The security token returned by this method can be passed to the Windows API's GetTokenInformation function to obtain more information about the process.
Important: When applications are finished using the returned security token, they must close it using the Windows API's CloseHandle function.
Note: This method can only be called within events.
This method returns a Long64 value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
