<H2>DESCRIPTION</H2><PRE>
- The <B>printw</B>, <B>wprintw</B>, <B>mvprintw</B> and <B>mvwprintw</B> routines are
- analogous to <B>printf</B> [see <B><A HREF="printf.3S.html">printf(3S)</A></B>]. In effect, the
- string that would be output by <B>printf</B> is output instead as
- though <B>waddstr</B> were used on the given window.

- The <B>vwprintw</B> routine is analogous to <B>vprintf</B> [see
- <B><A HREF="printf.3S.html">printf(3S)</A></B>] and performs a <B>wprintw</B> using a variable argu-
- ment list. The third argument is a <B>va_list</B>, a pointer to
- a list of arguments, as defined in <B><varargs.h></B>.

<H2>RETURN VALUE</H2><PRE>
- Routines that return an integer return <B>ERR</B> upon failure
- and <B>OK</B> (SVr4 only specifies "an integer value other than
- <B>ERR</B>") 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.

<H2>PORTABILITY</H2><PRE>
- The XSI Curses standard, Issue 4 describes these func-
- tions. The function <B>vwprintw</B> is marked TO BE WITHDRAWN,
- and is to be replaced by a function <B>vw_printw</B> using the
- <B><stdarg.h></B> interface.

+ 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 is marked TO BE WITHDRAWN,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><stdarg.h></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><varargs.h></STRONG>, which
+ cannot be used in the same file as <STRONG><stdarg.h></STRONG>. This im-
+ plementation uses <STRONG><stdarg.h></STRONG> for both, because that header
+ is included in <STRONG><curses.h</STRONG>>.
