curs_in_wchstr(3X)                                    curs_in_wchstr(3X)

NAME         top

       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         top

       #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         top

       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         top

       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         top

       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         top

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