       get_wstr,   getn_wstr,	wget_wstr,   wgetn_wstr,  mvget_wstr,  mvgetn_wstr,  mvwget_wstr,
       mvwgetn_wstr - get an array of wide characters from a curses terminal keyboard

       #include <curses.h>

       int get_wstr(wint_t *wstr);
       int getn_wstr(wint_t *wstr, int n);
       int wget_wstr(WINDOW *win, wint_t *wstr);
       int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
       int mvget_wstr(int y, int x, wint_t *wstr);
       int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
       int mvwget_wstr(WINDOW *win, int y, int x, wint_t *wstr);
       int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);

       The effect of get_wstr is as though a series of calls to get_wch were made, until  a  new-
       line,  other end-of-line, or end-of-file condition is processed.  An end-of-file condition
       is represented by WEOF, as defined in <wchar.h>.  The newline and  end-of-line  conditions
       are  represented by the \n wchar_t value.  In all instances, the end of the string is ter-
       minated by a null wchar_t.  The routine places resulting values in the area pointed to  by

       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).

       The effect of wget_wstr is as though a series of calls to wget_wch were made.

       The effect of mvget_wstr is as though a call to move and then a series of calls to get_wch
       were made.

       The  effect  of	mvwget_wstr  is  as  though a call to wmove and then a series of calls to
       wget_wch were made.

       The getn_wstr, mvgetn_wstr, mvwgetn_wstr, and wgetn_wstr functions are  identical  to  the
       get_wstr,  mvget_wstr, mvwget_wstr, and wget_wstr functions, respectively, except that the
       *n_* versions read at most n characters, letting the application prevent overflow  of  the
       input buffer.

       Using  get_wstr,  mvget_wstr,  mvwget_wstr, or wget_wstr to read a line that overflows the
       array pointed to by wstr causes undefined results.  The	use  of  getn_wstr,  mvgetn_wstr,
       mvwgetn_wstr, or wgetn_wstr, respectively, is recommended.

       These  functions  cannot  return KEY_ values because there is no way to distinguish a KEY_
       value from a valid wchar_t value.

       All of these routines except wgetn_wstr may be macros.

       All of these functions return OK upon successful completion.  Otherwise, they return ERR.

       These functions are described in The Single Unix Specification, Version 2.  No error  con-
       ditions are defined.  This implementation returns ERR if the window pointer is null, or if
       the lower-level wget_wch call returns an ERR.  In the latter case, an ERR  return  without
       other  data is treated as an end-of-file condition, and the returned array contains a WEOF
       followed by a null wchar_t.

       Functions: curses(3X), curs_get_wch(3X), curs_getstr(3X).
