        These  routines  manipulate  the current attributes of the
-       named window.  The current attributes of a window apply to

-       <STRONG>ch</STRONG>, <STRONG>waddstr</STRONG> and <STRONG>wprintw</STRONG>.  Attributes are a property of the
-       character,   and  move  with  the  character  through  any
-       scrolling and insert/delete line/character operations.  To
-       the  extent  possible,  they  are displayed as appropriate
-       modifications to the graphic rendition of  characters  put
-       on the screen.
-
-       The  routine  <STRONG>attrset</STRONG>  sets  the current attributes of the
-       given window to <EM>attrs</EM>.  The routine <STRONG>attroff</STRONG> turns off  the
-       named  attributes  without turning any other attributes on
-       or off.  The routine <STRONG>attron</STRONG> turns on the named  attributes
-       without affecting any others.  The routine <STRONG>standout</STRONG> is the
-       same as <STRONG>attron(A_STANDOUT)</STRONG>.  The routine <STRONG>standend</STRONG>  is  the
-       same as <STRONG>attrset(A_NORMAL)</STRONG> or <STRONG>attrset(0)</STRONG>, that is, it turns
-       off all attributes.
-
-       The <STRONG>attrset</STRONG> and related routines do  not  affect  the  at-

-       by  the  color_pair_number. The parameter opts is reserved
-       for future use, applications must supply a null pointer.

+       The <STRONG>attr_set</STRONG> and <STRONG>wattr_set</STRONG> functions set the  current  at-
+       tributes  of  the given window to <EM>attrs</EM>, with color speci-
+       fied by <EM>pair</EM>.  X/Open specified  an  additional  parameter
+       <EM>opts</EM> which is unused in all implementations.
 
-       The routine <STRONG>wattr_get</STRONG> returns the  current  attribute  and
-       color pair for the given window; <STRONG>attr_get</STRONG> returns the cur-
-       rent attribute and color pair for <STRONG>stdscr</STRONG>.   The  remaining
-       <STRONG>attr_</STRONG>*  functions  operate  exactly like the corresponding
-       <STRONG>attr</STRONG>* functions, except that they take arguments  of  type
-       <STRONG>attr_t</STRONG> rather than <STRONG>int</STRONG>.
+       Use  <STRONG>attr_get</STRONG> and <STRONG>wattr_get</STRONG> to retrieve attributes for the

+       Most of the window attribute routines  are  extensions  of

+       same name, omitting an underscore (<STRONG>_</STRONG>).
+
+       The  <STRONG>attrset</STRONG>  routine  is  a legacy feature predating SVr4
+       curses but kept in X/Open Curses for the same reason  that
+       SVr4 curses kept it: compatibility.
+
+       The  remaining  <STRONG>attr</STRONG>*  functions  operate exactly like the
+       corresponding <STRONG>attr_</STRONG>* functions, except that they take  ar-
+       guments of type <STRONG>int</STRONG> rather than <STRONG>attr_t</STRONG>.
+
+       There  is  no  corresponding  <STRONG>attrget</STRONG>  function as such in

        The routine <STRONG>chgat</STRONG> changes the attributes of a given number

        the way to the end of the current line.  The <STRONG>wchgat</STRONG>  func-
        tion generalizes this to any window; the <STRONG>mvwchgat</STRONG> function
-       does a cursor move before acting.  In these functions, the
-       color  argument is a color-pair index (as in the first ar-
