<H2>DESCRIPTION</H2><PRE>
The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are
- analogous to <STRONG>printf</STRONG> [see <STRONG><A HREF="printf.3S.html">printf(3S)</A></STRONG>]. In effect, the
+ analogous to <STRONG>printf</STRONG> [see <STRONG><A HREF="printf.3.html">printf(3)</A></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><A HREF="printf.3S.html">printf(3S)</A></STRONG>] and perform a <STRONG>wprintw</STRONG> using a
+ <STRONG>vprintf</STRONG> [see <STRONG><A HREF="printf.3.html">printf(3)</A></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><stdarg.h></STRONG>.
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.

- sion 2 states that <STRONG>vw_printw</STRONG> is preferred to <STRONG>vwprintw</STRONG>
