  33 .LP
  34 The \fBfgetwc()\fR and \fBfgetwc_l()\fR functions obtain the next
  35 character (if present) from the input stream pointed to by \fIstream\fR,
  36 convert that to the corresponding wide-character code and advance the
  37 associated file position indicator for the stream (if defined).
  38 Whereas \fBfgetwc()\fR uses the current locale, \fBfgetwc_l()\fR uses the
  39 locale specified by \fIloc\R.
  40 .LP
  41 If an error occurs, the resulting value of the file position indicator for the
  42 stream is indeterminate.
  43 .LP
  44 The \fBfgetwc()\fR and \fBfgetwc_l()\fR functions may mark the \fBst_atime\fR
  45 field of the file
  46 associated with \fIstream\fR for update. The \fBst_atime\fR field will be
  47 marked for update by the first successful execution of \fBfgetwc()\fR,
  48 \fBfgetc\fR(3C), \fBfgets\fR(3C), \fBfgetws\fR(3C), \fBfread\fR(3C),
  49 \fBfscanf\fR(3C), \fBgetc\fR(3C), \fBgetchar\fR(3C), \fBgets\fR(3C), or
  50 \fBscanf\fR(3C) using \fIstream\fR that returns data not supplied by a prior
  51 call to \fBungetc\fR(3C) or \fBungetwc\fR(3C).

  54 Upon successful completion both functions return the
