+---------------

Informix (all versions from the old non-SQL version on) uses a modified
curses called "rdsterm".  You should have an include file called "rdsterm.h"
in the informix include directory.

Most portable:  save current position, use inch() to fetch characters from
the screen, restore cursor.  Only problem is, I don't think rdsterm includes
the curses inch() function.  If it does, any curses manual will give you the
details.

Less portable:

	scrdump()
	{
		int x, y;

		for (y = 0; y < LINES; y++)
			for (x = 0; x < COLS: x++)
				do_something_with(stdscr->_y[y][x]);
	}

The problem with this is that it uses an internal structure (_y).  Also, if
you lack rdsterm.h, you can't do it.  DO NOT TRY TO USE /usr/include/curses.h
FOR THIS!!!  Rdsterm uses a slightly different internal format for the WINDOW
structure.

I don't know of any other way to accomplish it.
