-<H2>DESCRIPTION</H2><PRE>
-       The <STRONG>getbegy</STRONG> and <STRONG>getbegx</STRONG> functions return the same data  as
-       <STRONG>getbegyx</STRONG>.
+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+       These  legacy functions are simpler to use than the X/Open Curses func-
+       tions:
 
 
-       The  <STRONG>getcury</STRONG> and <STRONG>getcurx</STRONG> functions return the same data as
-       <STRONG>getyx</STRONG>.
+       <STRONG>o</STRONG>   The <STRONG>getattrs</STRONG> function returns the same attribute data as <STRONG>wattr_get</STRONG>.
 
 
-       The <STRONG>getmaxy</STRONG> and <STRONG>getmaxx</STRONG> functions return the same data  as
-       <STRONG>getmaxyx</STRONG>.
+           However, <STRONG>getattrs</STRONG> returns an integer  (actually  a  <STRONG>chtype</STRONG>),  while
+           <STRONG>wattr_get</STRONG>  returns  the current color pair in a separate parameter.
+           In the wide-character library configuration, color  pairs  may  not
+           fit into a <STRONG>chtype</STRONG>, so <STRONG>wattr_get</STRONG> is the only way to obtain the color
+           information.
 
 
-       The  <STRONG>getpary</STRONG> and <STRONG>getparx</STRONG> functions return the same data as
-       <STRONG>getparyx</STRONG>.
+           Because <STRONG>getattrs</STRONG> returns the attributes in a single  parameter,  it
+           would  not  be possible for an application to distinguish that from
+           <STRONG>ERR</STRONG> (a <EM>-1</EM>).  If the window  parameter  is  null,  <STRONG>getattrs</STRONG>  returns
+           <STRONG>A_NORMAL</STRONG> (zero).
 
 
+       <STRONG>o</STRONG>   The <STRONG>getbegy</STRONG> and <STRONG>getbegx</STRONG> functions return the same data as <STRONG>getbegyx</STRONG>.
 
 
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
-       These functions return an integer, or ERR  if  the  window
-       parameter is null.
+       <STRONG>o</STRONG>   The <STRONG>getcury</STRONG> and <STRONG>getcurx</STRONG> functions return the same data as <STRONG>getyx</STRONG>.
 
 
+       <STRONG>o</STRONG>   The <STRONG>getmaxy</STRONG> and <STRONG>getmaxx</STRONG> functions return the same data as <STRONG>getmaxyx</STRONG>.
 
 
-</PRE>
-<H2>NOTES</H2><PRE>
-       All  of  these interfaces are provided as macros and func-
-       tions.  The macros are suppressed (and only the  functions
-       provided)  when  <STRONG>NCURSES_OPAQUE</STRONG>  is defined.  The standard
-       forms such as <STRONG>getyx</STRONG> must be implemented as macros, and (in
-       this implementation) are defined in terms of the functions
-       described here, to avoid reliance on internal  details  of
-       the WINDOW structure.
+       <STRONG>o</STRONG>   The <STRONG>getpary</STRONG> and <STRONG>getparx</STRONG> functions return the same data as <STRONG>getparyx</STRONG>.
 
 
 
 
-</PRE>
-<H2>PORTABILITY</H2><PRE>
-       These functions were supported on Version 7, BSD or System
-       V implementations.
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Except  as noted, these functions return an integer, or <STRONG>ERR</STRONG> if the win-
+       dow parameter is null.

+
+       The <STRONG>getattrs</STRONG> function and macro are defined to return a (signed)  inte-
+       ger  for  compatibility with those implementations although an unsigned
+       type would have been more appropriate.
