-<H2>DESCRIPTION</H2><PRE>
- The <STRONG>bkgrndset</STRONG> and <STRONG>wbkgrndset</STRONG> routines manipulate the back-
- ground of the named window. The window background is a
- <STRONG>cchar_t</STRONG> consisting of any combination of attributes (i.e.,
- rendition) and a complex character. The attribute part of
- the background is combined (OR'ed) with all non-blank
- characters that are written into the window with <STRONG>waddch</STRONG>.
- Both the character and attribute parts of the background
- are combined with the blank characters. The background
- becomes a property of the character and moves with the
- character through any scrolling and insert/delete
- line/character operations.
-
- To the extent possible on a particular terminal, the
- attribute part of the background is displayed as the
- graphic rendition of the character put on the screen.
-
- The <STRONG>bkgrnd</STRONG> and <STRONG>wbkgrnd</STRONG> functions set the background prop-
- erty of the current or specified window and then apply
- this setting to every character position in that window:
-
- The rendition of every character on the screen is
- changed to the new background rendition.
-
- Wherever the former background character appears,
- it is changed to the new background character.
-
- The <STRONG>getbkgrnd</STRONG> function returns the given window's current
- background character/attribute pair via the <STRONG>wch</STRONG> pointer.
