       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  car-
       riage  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

       wgetnstr reads at most n characters, thus preventing a possible overflow of the input buf-
       fer.  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  win-
       dow,  KEY_LEFT and KEY_BACKSPACE are both considered equivalent to the user's kill charac-

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

       All  routines return the integer ERR upon failure and an OK (SVr4 specifies only "an inte-
       ger 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

       SVr3  and early SVr4 curses implementations did not reject function keys; the SVr4.0 docu-
       mentation claimed that "special 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 present but not documented in SVr4.
