11 .TH WCWIDTH 3C "Aug 14, 2002"
12 .SH NAME
13 wcwidth, wcwidth_l \- number of column positions of a wide-character code
14 .SH SYNOPSIS
15 .LP

17 #include <wchar.h>

19 \fBint\fR \fBwcwidth\fR(\fBwchar_t\fR \fIwc\fR);

23 .SH DESCRIPTION
24 .sp
25 .LP
26 The \fBwcwidth()\fR function determines the number of column positions required
27 for the wide character \fIwc\fR. The value of \fIwc\fR must be a character
28 representable as a \fBwchar_t\fR, and must be a wide-character code
29 corresponding to a valid character in the current locale.
30 .sp
31 .LP
32 The function \fBwcwidth_l()\fR behaves identically to \fBwcwidth()\fR, except
33 instead of operating in the current environemtn, it operates in the environment
34 specified by \fIloc\fR.
35 .SH RETURN VALUES
36 .SH RETURN VALUES
37 .sp
38 .LP
39 The \fBwcwidth()\fR function either returns \fB0\fR (if \fIwc\fR is a null
40 wide-character code), or returns the number of column positions to be occupied
41 by the wide-character code \fIwc\fR, or returns \fB\(mi1\fR (if \fIwc\fR does
42 not correspond to a printing wide-character code).
