.SH NAME
wctob \- try to represent a wide character as a single byte
.SH SYNOPSIS
.nf
.B #include <wchar.h>
.sp
.BI "int wctob(wint_t " c );
.fi
.SH DESCRIPTION
The
.BR wctob ()
function tests whether
the multi-byte representation of the
wide character \fIc\fP, starting in the initial state, consists of a single
byte.
If so, it is returned as an unsigned char.
.PP
Never use this function.
It cannot help you in writing internationalized
programs.
Internationalized programs must never distinguish single-byte and
multi-byte characters.
.SH "RETURN VALUE"
The
.BR wctob ()
function returns the single-byte representation of \fIc\fP,
if it exists, of EOF otherwise.
.SH "CONFORMING TO"
C99.
.SH NOTES
The behavior of
.BR wctob ()
depends on the
.B LC_CTYPE
category of the
current locale.
.PP
This function should never be used.
Internationalized programs must never
distinguish single-byte and multi-byte characters.
Use the function
.BR wctomb (3)
instead.
.SH "SEE ALSO"
.BR wctomb (3)
