-The \fBprintw\fR, \fBwprintw\fR, \fBmvprintw\fR and \fBmvwprintw\fR
-routines are analogous to \fBprintf\fR [see \fBprintf\fR(3)].

In

-instead as though \fBwaddstr\fR were used on the given window.

-The \fBvwprintw\fR and \fBvw_printw\fR routines are analogous
-to \fBvprintf\fR [see \fBprintf\fR(3)]
-and perform a \fBwprintw\fR using a variable argument list.
-The third argument is a \fBva_list\fR, a pointer to a
-list of arguments, as defined in \fB<stdarg.h>\fR.

.PP
X/Open defines no error conditions.
SVr3 also added \fBvwprintw\fP, saying that the third parameter
is a \fBva_list\fP, defined in <varargs.h>,
and referring the reader to the manual pages for \fIvarargs\fP and
-\fIvprintf\fP for detailed descriptions.
+\fBvprintf\fP for detailed descriptions.
.PP
SVr4 added no new variations of \fBprintw\fP,
but provided for using <varargs.h> or <stdarg.h> to define the \fBva_list\fP
.bP
The XSI Curses standard, Issue 4 described these functions.
The function
-\fBvwprintw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function
-\fBvw_printw\fR using the \fB<stdarg.h>\fR interface.

+\fBvw_printw\fP using the \fB<stdarg.h>\fP interface.
.bP
The Single Unix Specification, Version 2 states that
-\fBvw_printw\fR is preferred to \fBvwprintw\fR since the latter requires
-including \fB<varargs.h>\fR, which
-cannot be used in the same file as \fB<stdarg.h>\fR.
-This implementation uses \fB<stdarg.h>\fR for both,
-because that header is included in \fB<curses.h\fR>.

.bP
X/Open Curses, Issue 5 (December 2007) marked \fBvwprintw\fP (along with
\fBvwscanw\fP and the termcap interface) as withdrawn.
