.SH NAME
wsscanf \- formatted input conversion
.SH SYNOPSIS
.LP
.nf
#include<stdio.h>
#include <widec.h>

\fBint\fR \fBwsscanf\fR(\fBwchar_t *\fR\fIs\fR, \fBconst char *\fR\fIformat\fR, \fB/*\fR \fIpointer\fR */ ... );
.fi

.SH DESCRIPTION
.sp
.LP
The \fBwsscanf()\fR function reads Process Code characters from the Process
Code string \fIs\fR, interprets them according to the \fIformat\fR, and stores
the results in its arguments.  It expects, as arguments, a control string
\fIformat\fR, and a set of \fIpointer\fR arguments indicating where the
converted input should be stored. The results are undefined if there are
insufficient \fIarg\fRs for the format.  If the format is exhausted while
\fIarg\fRs remain, the excess \fIarg\fRs are simply ignored.
.sp
.LP
The conversion specifications and behavior of \fBwsscanf()\fR are the same as
the regular \fBsscanf\fR(3C) function except that the source is a Process Code
string for \fBwsscanf()\fR and on Extended Unix Code (EUC) character string for
\fBsscanf\fR(3C).
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBwsscanf()\fR returns the number of characters
matched. Otherwise, it returns a negative value.
