NAME
       getstr,	getnstr,  wgetstr,  wgetnstr, mvgetstr, mvgetnstr, mvwgetstr,
       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 spec-
       ifies only "an integer value other than ERR") upon successful  comple-
       tion.

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
       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.
