NAME
wctob - try to represent a wide character as a single byte
LIBRARY
Standard C library
(libc, -lc)
SYNOPSIS
#include <wchar.h>
int wctob(wint_t c);
DESCRIPTION
The
wctob()
function tests whether
the multibyte representation of the
wide character
c,
starting in the initial state, consists of a single
byte.
If so, it is returned as an
unsigned char.
Never use this function.
It cannot help you in writing internationalized
programs.
Internationalized programs must never distinguish single-byte and
multibyte characters.
RETURN VALUE
The
wctob()
function returns the single-byte representation of
c,
if it exists, or
EOF
otherwise.
ATTRIBUTES

NOTES
The behavior of
wctob()
depends on the
LC_CTYPE
category of the
current locale.
This function should never be used.
Internationalized programs must never
distinguish single-byte and multibyte characters.
Use either
wctomb(3)
or the thread-safe
wcrtomb(3)
instead.
