.Sh DESCRIPTION
|
|
These functions manipulate the background attributes on
|
|
.Dv stdscr
|
|
or on the specified window.
|
|
.Pp
|
|
The function
|
|
.Fn wbkgdset win ch
|
|
sets the background attributes of the specified window
|
|
.Fa win
|
|
to
|
|
.Fa ch .
|
|
.Pp
|
|
When the background attributes are set on a window, characters are added to
|
|
the window with the logical
|
|
.Em 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.
|
|
.Pp
|
|
Note that subwindows created from
|
|
.Fa win
|
|
inherit the background attributes of
|
|
.Fa win .
|
|
.Pp
|
|
The function
|
|
.Fn wbkgd win ch
|
|
sets the background attributes of the specified window
|
|
.Fa win
|
|
to
|
|
.Fa ch
|
|
and also sets the rendition of every character position on that window,
|
|
as if the characters had been newly added to
|
|
.Fa win .
|
|
The rendition of characters on subwindows of
|
|
.Fa win
|
|
is also set to
|
|
.Fa ch .
|
|
.Pp
|
|
The functions
|
|
.Fn bkgdset ch
|
|
and
|
|
.Fn bkgd ch
|
|
are equivalent to
|
|
.Fn wbkgdset stdscr ch
|
|
and
|
|
.Fn wbkgd stdscr ch ,
|
|
respectively.
|
|
.Pp
|
|
The function
|
|
.Fn getbkgd win
|
|
returns the background attributes for the window
|
|
.Fa win .
|
|
.Sh RETURN VALUES
|
|
The functions
|
|
.Fn wbkgdset
|
|
and
|
|
.Fn wbkgd
|
|
return OK on success and ERR on failure.
