If there is data offscreen to the right of the current field of the given
form then data_ahead() will return TRUE, otherwise FALSE is returned.
Similarly, if there is data offscreen to the left of the current field of
the given form then data_behind() will return TRUE.
If the condition is met then the functions will return TRUE, if there is
an error or there is no data offscreen the functions will return FALSE.
The header <form.h> automatically includes both <curses.h> and <eti.h>.
