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 either mbtowc(3) or the thread-safe mbrtowc(3) instead.
