NAME

       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

SYNOPSIS

       #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);

DESCRIPTION

       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
       characters.

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

NOTES

       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.

RETURN VALUE

       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.

PORTABILITY

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