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

  22 .SH DESCRIPTION
  23 .sp
  24 .LP
  25 The \fBwcwidth()\fR function determines the number of column positions required
  26 for the wide character \fIwc\fR. The value of \fIwc\fR must be a character
  27 representable as a \fBwchar_t\fR, and must be a wide-character code
  28 corresponding to a valid character in the current locale.




  29 .SH RETURN VALUES
  30 .sp
  31 .LP
  32 The \fBwcwidth()\fR function either returns \fB0\fR (if \fIwc\fR is a null
  33 wide-character code), or returns the number of column positions to be occupied
  34 by the wide-character code \fIwc\fR, or returns \fB\(mi1\fR (if \fIwc\fR does
  35 not correspond to a printing wide-character code).

  12 .TH WCWIDTH 3C "Jun 25, 2014"
  13 .SH NAME
  14 wcwidth, wcwidth_l \- number of column positions of a wide-character code
  15 .SH SYNOPSIS
  16 .LP
  17 .nf
  18 #include <wchar.h>
  19 
  20 \fBint\fR \fBwcwidth\fR(\fBwchar_t\fR \fIwc\fR);

  28 .fi
  29 .SH DESCRIPTION

  30 .LP
  31 The \fBwcwidth()\fR function determines the number of column positions required
  32 for the wide character \fIwc\fR. The value of \fIwc\fR must be a character
  33 representable as a \fBwchar_t\fR, and must be a wide-character code
  34 corresponding to a valid character in the current locale.
  35 .LP
  36 The function \fBwcwidth_l()\fR behaves identically to \fBwcwidth()\fR, except
  37 instead of operating in the current locale, it operates in the locale
  38 specified by \fIloc\fR.
  39 .SH RETURN VALUES

  40 .LP
  41 These functions either return \fB0\fR (if \fIwc\fR is a null
  42 wide-character code), or the number of column positions to be occupied
  43 by the wide-character code \fIwc\fR, or \fB\(mi1\fR (if \fIwc\fR does
  44 not correspond to a printing wide-character code).
