All the new types like <STRONG>Window</STRONG>, <STRONG>Panel</STRONG>,
<STRONG>Menu</STRONG>, <STRONG>Form</STRONG> etc. are just

<STRONG>WINDOW *</STRONG>, <STRONG>PANEL *</STRONG>,
<STRONG>MENU *</STRONG> or <STRONG>FORM *</STRONG>.
So you can safely pass them to C routines that expect a pointer
it in a way, that uses the line parameter also to control the amount of
lines to steal. This mechanism is used in the <STRONG>Rip_Off_Lines</STRONG>
routine of the binding.

<H4>Enumeration fields handling</H4>
The (n)curses documentation says, that the String arrays to be passed to
an TYPE_ENUM fieldtype must not be automatic variables. This is not true
in this binding, because it is internally arranged to safely copy these
values.

Basically it should not be too hard to make all this run on a regular SVr4
Most likely you will follow a mixed approach. Some features are easy to simulate,
others will be hard if not impossible.</LI>
