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.
