The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are
analogous to <STRONG>printf</STRONG> [see <STRONG>printf(3)</STRONG>]. In effect, the
string that would be output by <STRONG>printf</STRONG> is output instead as
though <STRONG>waddstr</STRONG> were used on the given window.
The <STRONG>vwprintw</STRONG> and <STRONG>wv_printw</STRONG> routines are analogous to
<STRONG>vprintf</STRONG> [see <STRONG>printf(3)</STRONG>] and perform a <STRONG>wprintw</STRONG> using a
variable argument list. The third argument is a <STRONG>va_list</STRONG>,
a pointer to a list of arguments, as defined in
<STRONG>&lt;stdarg.h&gt;</STRONG>.
</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
Routines that return an integer return <STRONG>ERR</STRONG> upon failure
and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value other than
<STRONG>ERR</STRONG>") upon successful completion.
X/Open defines no error conditions. In this implementa-
tion, an error may be returned if it cannot allocate
enough memory for the buffer used to format the results.
It will return an error if the window pointer is null.
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.
</PRE>
<H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
The XSI Curses standard, Issue 4 describes these func-
tions. The function <STRONG>vwprintw</STRONG> is marked TO BE WITHDRAWN,
and is to be replaced by a function <STRONG>vw_printw</STRONG> using the
<STRONG>&lt;stdarg.h&gt;</STRONG> interface. The Single Unix Specification, Ver-
sion 2 states that <STRONG>vw_printw</STRONG> is preferred to <STRONG>vwprintw</STRONG>
since the latter requires including <STRONG>&lt;varargs.h&gt;</STRONG>, which
cannot be used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>. This im-
plementation uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because that header
is included in <STRONG>&lt;curses.h</STRONG>&gt;.
