10 10 .TH GETWC 3C "Jul 24, 2002"

23 29 .SH DESCRIPTION
24 30 .sp
25 31 .LP
26 32 The \fBgetwc()\fR function is equivalent to \fBfgetwc\fR(3C), except that if it
27 33 is implemented as a macro it may evaluate \fIstream\fR more than once, so the
28 -argument should never be an expression with side effects. The
29 -\fBgetwc_l\fR function is similar to \fBfgetwc\fR, except instead of
30 -acting on the current locale as specified by \fBsetlocale\fR(3C) and
31 -\fBuselocale\fR(3C), it uses the locale specified by \fIloc\fR.
34 +argument should never be an expression with side effects.

36 +The \fBgetwc_l()\fR function is similar to \fBgetwc()\fR, except instead of
37 +acting on the current locale, it uses the locale specified by \fIloc\fR.
32 38 .SH RETURN VALUES

34 39 .LP
35 40 Refer to \fBfgetwc\fR(3C).

40 44 .SH USAGE
41 -.sp
42 45 .LP
43 46 This interface is provided to align with some current implementations and with
44 47 possible future \fBISO\fR standards.
45 -.sp
46 48 .LP
47 -Because it may be implemented as a macro, \fBgetwc()\fR may treat incorrectly a
48 -\fIstream\fR argument with side effects. In particular,
49 -\fBgetwc\fR(*\fIf\fR\|++) may not work as expected. Therefore, use of this
50 -function is not recommended; \fBfgetwc\fR(3C) should be used instead.
