stdscr or on the specified window.
The function
    wbkgdset(win,
    ch) sets the background attributes of the specified
    window win to ch.
When the background attributes are set on a window, characters are added to the window with the logical OR of the background attributes and the character's attributes. If both the background attribute and the character attribute contain color, the color of the character attribute is rendered. If the background attribute contains a non-space character, then this character is added where the foreground character is a space character.
Note that subwindows created from win inherit the background attributes of win.
The function
    wbkgd(win,
    ch) sets the background attributes of the specified
    window win to ch and also sets
    the rendition of every character position on that window, as if the
    characters had been newly added to win. The rendition
    of characters on subwindows of win is also set to
    ch.
The functions
    bkgdset(ch) and
    bkgd(ch) are equivalent to
    wbkgdset(stdscr,
    ch) and
    wbkgd(stdscr,
    ch), respectively.
The function
    getbkgd(win) returns the
    background attributes for the window win.
wbkgdset() and
  wbkgd() return OK on success and ERR on failure.
