11 .SH NAME
12 getwc, getwc_l \- get wide character from a stream
13 .SH SYNOPSIS
14 .LP
15 .nf
16 #include <stdio.h>
17 #include <wchar.h>
18
19 \fBwint_t\fR \fBgetwc\fR(\fBFILE\fR \fI*stream\fR);
20 \fBwint_t\fR \fBgetwc_l\fR(\fBFILE\fR \fI*stream\fR, \fBlocale_t\fR \fIloc\fR);
21 .fi
22
23 .SH DESCRIPTION
24 .sp
25 .LP
26 The \fBgetwc()\fR function is equivalent to \fBfgetwc\fR(3C), except that if it
27 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.
32 .SH RETURN VALUES
33 .sp
34 .LP
35 Refer to \fBfgetwc\fR(3C).
36 .SH ERRORS
37 .sp
38 .LP
39 Refer to \fBfgetwc\fR(3C).
40 .SH USAGE
41 .sp
42 .LP
43 This interface is provided to align with some current implementations and with
44 possible future \fBISO\fR standards.
45 .sp
46 .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.
