   * BadSource: connect_socket Read data using a connect socket (client side)
   * GoodSource: Full path and file name
   * Sinks: ofstream
   *    BadSink : Open the file named in data using ofstream::open()
   * Flow Variant: 74 Data flow: data passed in a map from one function to another in different source files
