curs_getstr(3X)						       curs_getstr(3X)

       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 over-
       flow of the input buffer.  Any attempt to enter more characters	(other
       than  the terminating newline or	carriage return) causes	a beep.	 Func-
       tion 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 previous character	(typi-
       cally a left motion).

       All routines return the integer ERR upon	failure	and an OK (SVr4	speci-
       fies only "an integer value other than ERR")  upon  successful  comple-

       X/Open defines no error conditions.

       In  this	 implementation, these functions return	an error if the	window
       pointer is null,	or if its timeout expires without having any data.

       This implementation provides an extension as well.  If a	 SIGWINCH  in-
       terrupts	the function, it will return KEY_RESIZE	rather than OK or ERR.

       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  "special  keys"  (such  as
       function	 keys, "home" key, "clear" key,	etc.) are "interpreted", with-
       out 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 present  but  not
       documented in SVr4.
