! .TH GETWC 3C "Jul 24, 2002"
  .SH NAME
! getwc \- get wide character from a stream
  .SH SYNOPSIS
  .LP
  .nf
  #include <stdio.h>
  #include <wchar.h>
  
  \fBwint_t\fR \fBgetwc\fR(\fBFILE\fR \fI*stream\fR);
  .fi
  
  .SH DESCRIPTION
  .sp
  .LP
  The \fBgetwc()\fR function is equivalent to \fBfgetwc\fR(3C), except that if it
  is implemented as a macro it may evaluate \fIstream\fR more than once, so the
  argument should never be an expression with side effects.
  .SH RETURN VALUES
- .sp
  .LP
  Refer to \fBfgetwc\fR(3C).
  .SH ERRORS
- .sp
  .LP
  Refer to \fBfgetwc\fR(3C).
  .SH USAGE
- .sp
  .LP
  This interface is provided to align with some current implementations and with
  possible future \fBISO\fR standards.
- .sp
  .LP
! Because it may be implemented as a macro, \fBgetwc()\fR may treat incorrectly a
! \fIstream\fR argument with side effects.  In particular,
! \fBgetwc\fR(*\fIf\fR\|++) may not work as expected.  Therefore, use of this
! function is not recommended; \fBfgetwc\fR(3C) should be used instead.
