.SH DESCRIPTION
The \fBprintw\fR, \fBwprintw\fR, \fBmvprintw\fR and \fBmvwprintw\fR
-routines are analogous to \fBprintf\fR [see \fBprintf\fR(3S)]. In
+routines are analogous to \fBprintf\fR [see \fBprintf\fR(3)]. In
effect, the string that would be output by \fBprintf\fR is output
instead as though \fBwaddstr\fR were used on the given window.

+.PP
The \fBvwprintw\fR and \fBwv_printw\fR routines are analogous
-to \fBvprintf\fR [see \fBprintf\fR(3S)]
+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.
Routines that return an integer return \fBERR\fR upon failure and \fBOK\fR
(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful
completion.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+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.
.SH PORTABILITY
The XSI Curses standard, Issue 4 describes these functions. The function
\fBvwprintw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function
This implementation uses \fB<stdarg.h>\fR for both, because that header
is included in \fB<curses.h\fR>.
