.SH NAME
\fBscanw\fR,
\fBwscanw\fR,
\fBmvscanw\fR,
\fBmvwscanw\fR,
-\fBvwscanw\fR, \fBvw_scanw\fR - convert formatted input from a \fBcurses\fR window
+\fBvwscanw\fR, \fBvw_scanw\fR \- convert formatted input from a \fBcurses\fR window
.SH SYNOPSIS
\fB#include <curses.h>\fR
-
+.sp
\fBint scanw(char *fmt, ...);\fR
.br
\fBint wscanw(WINDOW *win, char *fmt, ...);\fR
\fBint vwscanw(WINDOW *win, char *fmt, va_list varglist);\fR
.SH DESCRIPTION
The \fBscanw\fR, \fBwscanw\fR and \fBmvscanw\fR routines are analogous to
-\fBscanf\fR [see \fBscanf\fR(3S)]. The effect of these routines is as though
+\fBscanf\fR [see \fBscanf\fR(3)]. The effect of these routines is as though
\fBwgetstr\fR were called on the window, and the resulting line used as input
for \fBsscanf\fR(3). Fields which do not map to a variable in the \fIfmt\fR
field are lost.
-
+.PP
The \fBvwscanw\fR and \fBvw_scanw\fR routines are analogous to \fBvscanf\fR.
They perform a \fBwscanw\fR using a variable argument list.
The third argument is a \fIva_list\fR,
.SH RETURN VALUE
\fBvwscanw\fR returns \fBERR\fR on failure and an integer equal to the
number of fields scanned on success.
-
+.PP
Applications may use the return value from the \fBscanw\fR, \fBwscanw\fR,
\fBmvscanw\fR and \fBmvwscanw\fR routines to determine the number of fields
which were mapped in the call.
+.PP
+Functions with a "mv" prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
.SH PORTABILITY
The XSI Curses standard, Issue 4 describes these functions. The function
\fBvwscanw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function
One possible way to get useful results would be to use a "%n" conversion
at the end of the format string to ensure that something was processed.
