</PRE>
<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.


</PRE>
<H2>NOTES</H2><PRE>
       Note that <STRONG>bkgrnd</STRONG>, <STRONG>bkgrndset</STRONG>, and <STRONG>getbkgrnd</STRONG> may be  macros.


</PRE>
<H2>RETURN VALUES</H2><PRE>
       The  <STRONG>bkgrndset</STRONG>  and  <STRONG>wbkgrndset</STRONG>  routines  do not return a
       value.

       Upon successful completion, the other functions return <STRONG>OK</STRONG>.
       Otherwise,  they  return  <STRONG>ERR</STRONG>.   A  null window pointer is
       treated as an error.
