 Converts a Python object <tt>obj</tt> to a C pointer.  The result of the conversion is placed
 into the pointer located at <tt>ptr</tt>.  <tt>ty</tt> is a SWIG type descriptor structure.
 <tt>flags</tt> is used to handle error checking and other aspects of conversion.  It is the

-error.  The second flag additionally
