Obsolete Pointer Functions
==========================


.. function:: this_node


    Syntax:
    
        .. code-block::
            python

            h.this_node(x)            
            h.this_node(x, sec=section)


    Description:
        Return a pointer (coded as a double) to the segment 
        of *section* that 
        contains location *x*.
        If no section is specified, it uses the currently accessed section; see
        :func:`cas`. If you wish to compute a segment number 
        index where 1 is the first nonzero area segment and :data:`nseg` is the last 
        nonzero area segment 
        of the currently accessed section corresponding to position x use the 
        hoc function 


    .. warning::
        This function is useless and should be removed.

.. function:: this_section


    Syntax:
    
        .. code-block::
            python
            
            h.this_section(x)



    Description:
        Return a pointer (coded as a double) to the section which contains location 0 of the 
        currently accessed section. This pointer can be used as the argument 
        to :func:`push_section`. Functions that return pointers coded as doubles 
        are unsafe with 64 bit pointers. This function has been superseded by 
        :class:`SectionRef` and in Python the use of Section objects.
        
    See :meth:`~SectionRef.sec`.
