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.
