-.SH NAME
-btowc \- convert single byte to wide character
-.SH SYNOPSIS
-.nf
-.B #include <wchar.h>
-.sp
-.BI "wint_t btowc(int " c );
-.fi
-.SH DESCRIPTION
-The
-.BR btowc ()
-function converts \fIc\fP,
-interpreted as a multibyte sequence
-of length 1, starting in the initial shift state, to a wide character and
-returns it.
-If \fIc\fP is
-.B EOF
-or not a valid multibyte sequence of length 1,
-the
-.BR btowc ()
-function returns
-.BR WEOF .
-.SH RETURN VALUE
-The
-.BR btowc ()
-function returns the wide character
-converted from the single byte \fIc\fP.
-If \fIc\fP is
-.B EOF
-or not a valid multibyte sequence of length 1,
-it returns
-.BR WEOF .
-.SH CONFORMING TO
-C99, POSIX.1-2001.
-.SH NOTES
-The behavior of
-.BR btowc ()
-depends on the
-.B LC_CTYPE
-category of the
-current locale.
-.PP
-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
-.BR mbtowc (3)
-or the thread-safe
-.BR mbrtowc (3)
-instead.
