72        The <STRONG>bkgrndset</STRONG> and <STRONG>wbkgrndset</STRONG> routines manipulate the back-
73        ground of the named window.  The window  background  is  a
74        <STRONG>cchar_t</STRONG> consisting of any combination of attributes (i.e.,
75        rendition) and a complex character.  The attribute part of
76        the  background  is  combined  (OR'ed)  with all non-blank
77        characters that are written into the window  with  <STRONG>waddch</STRONG>.
78        Both  the  character and attribute parts of the background
79        are combined with the blank  characters.   The  background
80        becomes  a  property  of  the character and moves with the
81        character  through   any   scrolling   and   insert/delete
82        line/character operations.
83
84        To  the  extent  possible  on  a  particular terminal, the
85        attribute part of  the  background  is  displayed  as  the
86        graphic rendition of the character put on the screen.

91        The  <STRONG>bkgrnd</STRONG> and <STRONG>wbkgrnd</STRONG> functions set the background prop-
92        erty of the current or specified  window  and  then  apply
93        this setting to every character position in that window:
94
95        <STRONG>o</STRONG>   The  rendition  of  every  character  on the screen is
96            changed to the new background rendition.
97
98        <STRONG>o</STRONG>   Wherever the former background character  appears,  it
99            is changed to the new background character.

103 <H3><a name="h3-getbkgrnd">getbkgrnd</a></H3><PRE>
104        The  <STRONG>getbkgrnd</STRONG> function returns the given window's current
105        background character/attribute pair via the <STRONG>wch</STRONG> pointer.

115        The <STRONG>bkgrndset</STRONG> and <STRONG>wbkgrndset</STRONG>  routines  do  not  return  a
116        value.
117
118        Upon successful completion, the other functions return <STRONG>OK</STRONG>.
119        Otherwise, they return <STRONG>ERR</STRONG>.   A  null  window  pointer  is
120        treated as an error.
