  22   31  .SH DESCRIPTION
  23   32  .sp
  24   33  .LP
  25   34  The \fBgetwc()\fR function is equivalent to \fBfgetwc\fR(3C), except that if it
  26   35  is implemented as a macro it may evaluate \fIstream\fR more than once, so the
  27   36  argument should never be an expression with side effects.
       37 +.LP
       38 +The \fBgetwc_l()\fR function is similar to \fBgetwc()\fR, except instead of
       39 +acting on the current locale, it uses the locale specified by \fIloc\fR.
  28   40  .SH RETURN VALUES
  29      -.sp
  30   41  .LP
  31   42  Refer to \fBfgetwc\fR(3C).
  32   43  .SH ERRORS
  33      -.sp
  34   44  .LP
  35   45  Refer to \fBfgetwc\fR(3C).
  36   46  .SH USAGE
  37      -.sp
  38   47  .LP
  39   48  This interface is provided to align with some current implementations and with
  40   49  possible future \fBISO\fR standards.
  41      -.sp
  42   50  .LP
  43      -Because it may be implemented as a macro, \fBgetwc()\fR may treat incorrectly a
  44      -\fIstream\fR argument with side effects.  In particular,
  45      -\fBgetwc\fR(*\fIf\fR\|++) may not work as expected.  Therefore, use of this
  46      -function is not recommended; \fBfgetwc\fR(3C) should be used instead.

       55 +should be used instead.
