curses_background, bkgd, bkgdset, getbkgd, wbkgd, wbkgdset -- curses attribute manipulation
Curses Library (libcurses, -lcurses)
These functions manipulate the background attributes on stdscr or on the specified window.
The function wbkgdset(win, ch) sets the background attributes of the specified window win to
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
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.
The functions wbkgdset() and wbkgd() return OK on success and ERR on failure.
