       in_wchstr, in_wchnstr, win_wchstr, win_wchnstr, mvin_wchstr, mvin_wchnstr, mvwin_wchstr,
       mvwin_wchnstr - get an array of complex characters and renditions from a curses window

       #include <curses.h>

       int in_wchstr(cchar_t *wchstr);
       int in_wchnstr(cchar_t *wchstr, int n);
       int win_wchstr(WINDOW *win, cchar_t *wchstr);
       int win_wchnstr(WINDOW *win, cchar_t *wchstr, int n);
       int mvin_wchstr(int y, int x, cchar_t *wchstr);
       int mvin_wchnstr(int y, int x, cchar_t *wchstr, int n);
       int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wchstr);
       int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wchstr, int n);

       These functions return an array of complex characters in wchstr, starting at  the  current
       cursor  position  in the named window.  Attributes (rendition) are stored with the charac-

       The in_wchnstr, mvin_wchnstr, mvwin_wchnstr and win_wchnstr fill the array with at most	n
       cchar_t elements.

       Note that all routines except win_wchnstr may be macros.

       Reading	a line that overflows the array pointed to by wchstr with in_wchstr, mvin_wchstr,
       mvwin_wchstr or win_wchstr causes undefined results. Therefore,	the  use  of  in_wchnstr,
       mvin_wchnstr, mvwin_wchnstr, or win_wchnstr is recommended.

       Upon successful completion, these functions return OK.  Otherwise, they return ERR.

       Functions  with	a  "mv" prefix first perform a cursor movement using wmove, and return an
       error if the position is outside the window, or if the window pointer is null.

       The XSI Curses defines no error conditions.  This implementation checks for null pointers,
       returning ERR in that case.

       Functions: curses(3X), curs_in_wch(3X), curs_instr(3X), curs_inwstr(3X) curs_inchstr(3X)
