+ Name: inch
+
+ 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.
