Get a string from the terminal screen, store it in the variable
    str, and echo it on the specified window. The getstr function
    works on the stdscr window.

    Format

      #include  <curses.h>

      int getstr  (char *str);

      int wgetstr  (WINDOW *win, char *str);

1 - Arguments

 win

    A pointer to the window.

 str

    Must be large enough to hold the character string fetched from
    the window.

2 - Description

    The getstr and wgetstr functions refresh the specified window
    before fetching a string. The new-line terminator is stripped
    from the fetched string. For more information, see the scrollok
    function.

3 - Return Values

    OK                 Indicates success.
    ERR                Indicates that the function makes the screen
                       scroll illegally.
