btowc - convert single byte to wide character
SYNOPSIS
#include <wchar.h>
wint_t btowc (int c);
DESCRIPTION
The btowc function converts c, interpreted as a multibyte
sequence of length 1, starting in the initial shift state,
to a wide character and returns it. If c is EOF or not a
valid multibyte sequence of length 1, the btowc function
returns WEOF.
RETURN VALUE
The btowc function returns the wide character converted
from the single byte c. If c is EOF or not a valid multi
byte sequence of length 1, it returns WEOF.
CONFORMING TO

SEE ALSO
mbtowc(3)
NOTES
The behaviour of btowc depends on the LC_CTYPE category of
the current locale.
This function should never be used. It does not work for
encodings which have state, and unnecessarily treats sin
gle bytes differently from multibyte sequences. Use the
function mbtowc instead.
