On my Sun 3/80 SunOS 4.0.3 in case it matters, I'm having
trouble with the overlay() function.  Namely it seems to
do the same thing as overwrite()  (replaces the contents
of it's second arg by the contents of its first.)

Here's some code:


#include <curses.h>

main()
{
    WINDOW *win1, *win2;
    char c;

    initscr();
    crmode();
    win1=newwin(LINES, COLS, 0, 0);
    win2=newwin(LINES, COLS, 0, 0);
    wmove(win1, 10, 10) ; waddstr(win1, "this is window number one");
    wmove(win2, 20, 20) ; waddstr(win2, "this is window number two");

    wrefresh(win1);        /* show win one  */

    c=getchar();clear();refresh();
    wrefresh(win2);        /* show win two  */

    c=getchar();clear();refresh();
    overlay(win1, win2);   /* overlay */
    wrefresh(win2);        /* unfortunately, when it shows win2 here,
                              it looks just like win1 did before :-( */

    c=getchar();clear();refresh();
    endwin();

    return;
}

TFM wasn't helpful.
I would appreciate any emailed suggestions!
