NAME
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 sin-
gle byte c. If c is EOF or not a valid multibyte sequence of length 1,
it returns WEOF.
CONFORMING TO
C99, POSIX.1-2001.
NOTES
The behavior 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 single bytes differently
from multibyte sequences. Use either mbtowc(3) or the thread-safe mbr-
towc(3) instead.
