+  Synopsis:
+        int bkgd(chtype ch);
+        void bkgdset(chtype ch);
+        chtype getbkgd(WINDOW *win);
+        int wbkgd(WINDOW *win, chtype ch);
+        void wbkgdset(WINDOW *win, chtype ch);
+
+        int bkgrnd(const cchar_t *wch);
+        void bkgrndset(const cchar_t *wch);
+        int getbkgrnd(cchar_t *wch);
+        int wbkgrnd(WINDOW *win, const cchar_t *wch);
+        void wbkgrndset(WINDOW *win, const cchar_t *wch);
+        int wgetbkgrnd(WINDOW *win, cchar_t *wch);
+
+  Description:
+        bkgdset() and wbkgdset() manipulate the background of a window.
+        The background is a chtype consisting of any combination of
+        attributes and a character; it is combined with each chtype
+        added or inserted to the window by waddch() or winsch(). Only
+        the attribute part is used to set the background of non-blank
+        characters, while both character and attributes are used for
+        blank positions.
+
+        bkgd() and wbkgd() not only change the background, but apply it
+        immediately to every cell in the window.
+
+        The attributes that are defined with the attrset()/attron() set
+        of functions take precedence over the background attributes if
+        there is a conflict (e.g., different color pairs).
+
+  Return Value:
+        bkgd() and wbkgd() return OK, unless the window is NULL, in
+        which case they return ERR.
