  22 .SH DESCRIPTION
  23 .sp
  24 .LP
  25 The \fBwcswidth()\fR function determines the number of column positions
  26 required for \fIn\fR wide-character codes (or fewer than \fIn\fR wide-character
  27 codes if a null wide-character code is encountered before \fIn\fR
  28 wide-character codes are exhausted) in the string pointed to by \fIpwcs\fR.
  29 .SH RETURN VALUES
  30 .sp
  31 .LP
  32 The \fBwcswidth()\fR function either returns \fB0\fR (if \fIpwcs\fR points to a
  33 null wide-character code), or returns the number of column positions to be
  34 occupied by the wide-character string pointed to by \fIpwcs\fR, or returns
  35 \fB\(mi1\fR (if any of the first \fIn\fR wide-character codes in the
  36 wide-character string pointed to by \fIpwcs\fR is not a printing wide-character
  37 code).

  30 .SH DESCRIPTION
  31 .sp
  32 .LP
  33 The \fBwcswidth()\fR function determines the number of column positions
  34 required for \fIn\fR wide-character codes (or fewer than \fIn\fR wide-character
  35 codes if a null wide-character code is encountered before \fIn\fR
  36 wide-character codes are exhausted) in the string pointed to by \fIpwcs\fR.
  37 .SH RETURN VALUES

  38 .LP
  39 The \fBwcswidth()\fR function either returns \fB0\fR (if \fIpwcs\fR points to a
  40 null wide-character code), or returns the number of column positions to be
  41 occupied by the wide-character string pointed to by \fIpwcs\fR, or returns
  42 \fB\(mi1\fR (if any of the first \fIn\fR wide-character codes in the
  43 wide-character string pointed to by \fIpwcs\fR is not a printing wide-character
  44 code).
  45 .LP
  46 The function \fBwcwidth_l()\fR behaves identically to \fBwcwidth()\fR, except
  47 instead of operating in the current environemtn, it operates in the environment
  48 specified by \fIloc\fR.
