### Synopsis

    chtype inch(void);
    chtype winch(WINDOW *win);
    chtype mvinch(int y, int x);
    chtype mvwinch(WINDOW *win, int y, int x);

    int in_wch(cchar_t *wcval);
    int win_wch(WINDOW *win, cchar_t *wcval);
    int mvin_wch(int y, int x, cchar_t *wcval);
    int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);

### Description

   The inch() functions retrieve the character and attribute from
   the current or specified window position, in the form of a
   chtype. If a NULL window is specified, (chtype)ERR is returned.

   The in_wch() functions are the wide-character versions; instead
   of returning a chtype, they store a cchar_t at the address
   specified by wcval, and return OK or ERR. (No value is stored
   when ERR is returned.) Note that in PDCurses, chtype and cchar_t
   are the same.

### Portability
                             X/Open    BSD    SYS V
