(ctype)
Unregister the conversion from a ctype to its corresponding Objective-C type encoding.

    Note that this does not remove any conversions in the other direction (from an encoding to this ctype). These
    conversions may be replaced with :func:`register_encoding`, or unregistered with :func:`unregister_encoding`.
    To remove all encodings for a ctype, use :func:`unregister_ctype_all`.

    If the ctype was not registered previously, nothing happens.
Unregister the conversion from a ctype to its corresponding Objective-C type encoding.
