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 single 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 the function
mbtowc()
instead.
