63 <H2>DESCRIPTION</H2><PRE>
64        The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG>  routines  are
65        analogous  to  <STRONG>printf</STRONG>  [see  <STRONG><A HREF="printf.3S.html">printf(3S)</A></STRONG>].   In effect, the
66        string that would be output by <STRONG>printf</STRONG> is output instead as
67        though <STRONG>waddstr</STRONG> were used on the given window.
68
69        The  <STRONG>vwprintw</STRONG>  and  <STRONG>wv_printw</STRONG>  routines  are  analogous to
70        <STRONG>vprintf</STRONG> [see <STRONG><A HREF="printf.3S.html">printf(3S)</A></STRONG>] and perform  a  <STRONG>wprintw</STRONG>  using  a
71        variable  argument list.  The third argument is a <STRONG>va_list</STRONG>,
72        a  pointer  to  a  list  of  arguments,  as   defined   in
73        <STRONG>&lt;stdarg.h&gt;</STRONG>.

75
76 </PRE>
77 <H2>RETURN VALUE</H2><PRE>
78        Routines  that  return  an integer return <STRONG>ERR</STRONG> upon failure
79        and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value  other  than
80        <STRONG>ERR</STRONG>") upon successful completion.
81
82
83 </PRE>
84 <H2>PORTABILITY</H2><PRE>
85        The  XSI  Curses  standard,  Issue 4 describes these func-
86        tions.  The function <STRONG>vwprintw</STRONG> is marked TO  BE  WITHDRAWN,
87        and  is  to  be replaced by a function <STRONG>vw_printw</STRONG> using the
88        <STRONG>&lt;stdarg.h&gt;</STRONG> interface.  The Single Unix Specification, Ver-
89        sion  2  states  that  <STRONG>vw_printw</STRONG>  is preferred to <STRONG>vwprintw</STRONG>
90        since the latter  requires  including  <STRONG>&lt;varargs.h&gt;</STRONG>,  which
91        cannot  be  used  in  the  same  file as <STRONG>&lt;stdarg.h&gt;</STRONG>.  This
92        implementation uses  <STRONG>&lt;stdarg.h&gt;</STRONG>  for  both,  because  that
93        header is included in <STRONG>&lt;curses.h</STRONG>&gt;.
