11 .SH NAME

13 .SH SYNOPSIS
14 .LP
15 .nf
16 #include <stdio.h>
17 #include <wchar.h>

19 \fBint\fR \fBwctob\fR(\fBwint_t\fR \fIc\fR);

21 .fi

23 .SH DESCRIPTION
24 .sp
25 .LP
26 The \fBwctob()\fR function determines whether \fIc\fR corresponds to a member
27 of the extended character set whose character representation is a single byte
28 when in the initial shift state.
29 .sp
30 .LP
31 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
32 current locale. See \fBenviron\fR(5)
33 .sp
34 .LP
35 The function \fBwctob_l()\fR behaves identically to \fBwctob()\fR, except
36 instead of operating in the current environemtn, it operates in the environment
37 specified by \fIloc\fR.
38 .SH RETURN VALUES
39 .sp
40 .LP
41 The \fBwctob()\fR function returns \fBEOF\fR if \fIc\fR does not correspond to
42 a character with length one in the initial shift state. Otherwise, it returns
43 the single-byte representation of that character.
44 .SH ERRORS
45 .sp

47 No errors are defined.

72 .sp
73 .LP
74 The \fBwctob()\fR function can be used safely in multithreaded applications, as
75 long as \fBsetlocale\fR(3C) is not being called to change the locale.
