mvwgetnstr

       mvwgetnstr - accept character strings from curses terminal keyboard

SYNOPSIS
       #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);

DESCRIPTION
       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).

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

       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.

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

PORTABILITY
       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
