21 int in_wchstr(cchar_t *wch);
22 int in_wchnstr(cchar_t *wch, int n);
23 int win_wchstr(WINDOW *win, cchar_t *wch);
24 int win_wchnstr(WINDOW *win, cchar_t *wch, int n);
25 int mvin_wchstr(int y, int x, cchar_t *wch);
26 int mvin_wchnstr(int y, int x, cchar_t *wch, int n);

30 Description:
31 These routines read a chtype or cchar_t string from the window,
32 starting at the current or specified position, and ending at the
33 right margin, or after n elements, whichever is less.
34
35 Return Value:
36 All functions return the number of elements read, or ERR on
37 error.
