       getstr,  getnstr,  wgetstr, wgetnstr, mvgetstr, mvgetnstr,
       mvwgetstr, mvwgetnstr  -  accept  character  strings  from
       curses terminal keyboard


       #include <curses.h>

       int getstr(char *str);
       int getnstr(char *str, int n);
       int wgetstr(WINDOW *win, char *str);
       int wgetnstr(WINDOW *win, char *str, int n);
       int mvgetstr(int y, int x, char *str);
       int mvwgetstr(WINDOW *win, int y, int x, char *str);
       int mvgetnstr(int y, int x, char *str, int n);
       int mvwgetnstr(WINDOW *, int y, int x, char *str, int n);


       The  function getstr is equivalent to a series of calls to
       getch, until a newline or carriage return is received (the
       terminating  character  is  not  included  in the returned
       string).  The  resulting  value  is  placed  in  the  area
       pointed to by the character pointer str.

       wgetnstr  reads  at  most  n characters, thus preventing a
       possible overflow of the input  buffer.   Any  attempt  to
       enter  more characters (other than the terminating newline
       or carriage return) causes a  beep.   Function  keys  also
       cause  a beep and are ignored.  The getnstr function reads
       from the stdscr default window.

       The user's erase and kill characters are interpreted.   If
       keypad   mode   is   on   for  the  window,  KEY_LEFT  and
       KEY_BACKSPACE are both considered equivalent to the user's
       kill character.

       Characters  input are echoed only if echo is currently on.
       In that case, backspace is echoed as deletion of the  pre-
       vious character (typically a left motion).


       All routines return the integer ERR upon failure and an OK
       (SVr4 specifies only "an integer value  other  than  ERR")
       upon successful completion.


       Note that getstr, mvgetstr, and mvwgetstr may be macros.


       These  functions are described in the XSI Curses standard,
       Issue 4.  They  read  single-byte  characters  only.   The
       standard  does  not  define  any  error  conditions.  This
       implementation returns ERR if the window pointer is  null,
       or if the lower-level wgetch call returns an ERR.

       SVr3  and early SVr4 curses implementations did not reject
       function keys; the SVr4.0 documentation claimed that "spe-
       cial  keys"  (such  as  function keys, "home" key, "clear"
       key, etc.) are "interpreted", without giving details.   It
       lied.   In  fact,  the  `character'  value appended to the
       string by those implementations was  predictable  but  not
       useful  (being,  in  fact, the low-order eight bits of the
       key's KEY_ value).

       The functions getnstr, mvgetnstr, and mvwgetnstr were pre-
       sent but not documented in SVr4.
