- 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.
