.SH NAME
\fBscanw\fR,
\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.
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.
