  67        The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are  analogous  to
  68        <STRONG>printf</STRONG>  [see <STRONG>printf(3)</STRONG>].  In effect, the string that would be output by
  69        <STRONG>printf</STRONG> is output instead as though <STRONG>waddstr</STRONG> were used on the given  win-
  70        dow.
  71
  72        The  <STRONG>vwprintw</STRONG>  and  <STRONG>wv_printw</STRONG>  routines  are  analogous to <STRONG>vprintf</STRONG> [see
  73        <STRONG>printf(3)</STRONG>] and perform a <STRONG>wprintw</STRONG> using a variable argument  list.   The
  74        third  argument  is a <STRONG>va_list</STRONG>, a pointer to a list of arguments, as de-
  75        fined in <STRONG>&lt;stdarg.h&gt;</STRONG>.
  76
  77
  78 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  79        Routines that return an integer return <STRONG>ERR</STRONG> upon failure  and  <STRONG>OK</STRONG>  (SVr4
  80        only  specifies "an integer value other than <STRONG>ERR</STRONG>") upon successful com-
  81        pletion.
  82
  83        X/Open defines no error conditions.  In this implementation,  an  error
  84        may be returned if it cannot allocate enough memory for the buffer used
  85        to format the results.  It will return an error if the  window  pointer
  86        is null.
  87
  88        Functions  with  a  "mv"  prefix  first perform a cursor movement using
  89        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
  90        the window pointer is null.

  94        In  this implementation, <STRONG>vw_printw</STRONG> and <STRONG>vwprintw</STRONG> are equivalent, to sup-
  95        port legacy applications.  However, the latter (<STRONG>vwprintw</STRONG>) is obsolete:
  96
  97        <STRONG>o</STRONG>   The XSI Curses standard, Issue 4 described  these  functions.   The
  98            function  <STRONG>vwprintw</STRONG> is marked TO BE WITHDRAWN, and is to be replaced
  99            by a function <STRONG>vw_printw</STRONG> using the <STRONG>&lt;stdarg.h&gt;</STRONG> interface.
 100
 101        <STRONG>o</STRONG>   The Single Unix Specification, Version 2 states that <STRONG>vw_printw</STRONG>   is
 102            preferred   to   <STRONG>vwprintw</STRONG>   since  the  latter  requires  including
 103            <STRONG>&lt;varargs.h&gt;</STRONG>, which cannot be used in the same file  as  <STRONG>&lt;stdarg.h&gt;</STRONG>.
 104            This  implementation  uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because that header
 105            is included in <STRONG>&lt;curses.h</STRONG>&gt;.
 106
 107        <STRONG>o</STRONG>   X/Open Curses, Issue 5 (December 2007) marked <STRONG>vwprintw</STRONG> (along  with
 108            <STRONG>vwscanw</STRONG> and the termcap interface) as withdrawn.
