int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wchstr, int n);

int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wchstr);

DESCRIPTION

These functions extract characters from the current or specified window, starting at the current or specified position and ending at the end of the line, and place them in the array pointed to by wchstr .

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

RETURN VALUE

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

ERRORS

No errors are defined.

APPLICATION USAGE

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