  71        The  <STRONG>printw</STRONG>,  <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are
  72        analogous to  <STRONG>printf</STRONG>  [see  <STRONG>printf(3)</STRONG>].   In  effect,  the
  73        string that would be output by <STRONG>printf</STRONG> is output instead as
  74        though <STRONG>waddstr</STRONG> were used on the given window.
  75
  76        The <STRONG>vwprintw</STRONG>  and  <STRONG>wv_printw</STRONG>  routines  are  analogous  to
  77        <STRONG>vprintf</STRONG>  [see  <STRONG>printf(3)</STRONG>]  and  perform  a <STRONG>wprintw</STRONG> using a
  78        variable argument list.  The third argument is a  <STRONG>va_list</STRONG>,
  79        a   pointer   to  a  list  of  arguments,  as  defined  in
  80        <STRONG>&lt;stdarg.h&gt;</STRONG>.
  81

  84 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  85        Routines that return an integer return  <STRONG>ERR</STRONG>  upon  failure
  86        and  <STRONG>OK</STRONG>  (SVr4 only specifies "an integer value other than
  87        <STRONG>ERR</STRONG>") upon successful completion.
  88
  89        X/Open defines no error conditions.  In  this  implementa-
  90        tion,  an  error  may  be  returned  if it cannot allocate
  91        enough memory for the buffer used to format  the  results.
  92        It will return an error if the window pointer is null.
  93
  94        Functions  with a "mv" prefix first perform a cursor move-
  95        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
  96        outside the window, or if the window pointer is null.

 101        The  XSI  Curses  standard,  Issue 4 describes these func-
 102        tions.  The function <STRONG>vwprintw</STRONG> is marked TO  BE  WITHDRAWN,
 103        and  is  to  be replaced by a function <STRONG>vw_printw</STRONG> using the
 104        <STRONG>&lt;stdarg.h&gt;</STRONG> interface.  The Single Unix Specification, Ver-
 105        sion  2  states  that  <STRONG>vw_printw</STRONG>  is preferred to <STRONG>vwprintw</STRONG>
 106        since the latter  requires  including  <STRONG>&lt;varargs.h&gt;</STRONG>,  which
 107        cannot  be  used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>.  This im-
 108        plementation uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because that header
 109        is included in <STRONG>&lt;curses.h</STRONG>&gt;.
