form_data - test for off-screen data in given forms

#include <form.h>
bool data_ahead(const FORM *form);
bool data_behind(const FORM *form);

The function data_ahead tests whether there is off-screen data ahead in the given form. It returns TRUE (1) or FALSE (0).

The function data_behind tests whether there is off-screen data behind in the given form. It returns TRUE (1) or FALSE (0).

The header file <form.h> automatically includes the header file <curses.h>.

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
