NAME
btowc - convert single byte to wide character
SYNOPSIS
#include <wchar.h>
I wint_t btowc(int c );
DESCRIPTION
The
R 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
R btowc ()
function returns WEOF.
RETURN VALUE
The
R 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
R 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
R mbtowc ()
instead.
