Please check the C documentation
In short, you need to set an environment variable for defining the
directory where the .dot files should be dumped and then the filename
you provide to the function call is really just a filename (prefix).
You can use gst::debug_bin_to_dot_data() to get a string and handle the
writing yourself if you need more control. That function is also not
affected by the environment variable.
