70 <H2>DESCRIPTION</H2><PRE>
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><A HREF="printf.3S.html">printf(3S)</A></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.
76 The <STRONG>vwprintw</STRONG> and <STRONG>wv_printw</STRONG> routines are analogous to
77 <STRONG>vprintf</STRONG> [see <STRONG><A HREF="printf.3S.html">printf(3S)</A></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><stdarg.h></STRONG>.
84 <H2>RETURN VALUE</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.
91 <H2>PORTABILITY</H2><PRE>
92 The XSI Curses standard, Issue 4 describes these func-
93 tions. The function <STRONG>vwprintw</STRONG> is marked TO BE WITHDRAWN,
94 and is to be replaced by a function <STRONG>vw_printw</STRONG> using the
95 <STRONG><stdarg.h></STRONG> interface. The Single Unix Specification, Ver-
96 sion 2 states that <STRONG>vw_printw</STRONG> is preferred to <STRONG>vwprintw</STRONG>
97 since the latter requires including <STRONG><varargs.h></STRONG>, which
98 cannot be used in the same file as <STRONG><stdarg.h></STRONG>. This
99 implementation uses <STRONG><stdarg.h></STRONG> for both, because that
100 header is included in <STRONG><curses.h</STRONG>>.
