NAME
     btowc, btowc_l, wctob, wctob_l -- convert between wide and single-byte characters

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdio.h>
     #include <wchar.h>

     wint_t
     btowc(int c);

     int
     wctob(wint_t c);

     #include <wchar.h>
     #include <xlocale.h>

     wint_t
     btowc_l(int c, locale_t loc);

     int
     wctob_l(wint_t c, locale_t loc);

DESCRIPTION
     The btowc() function converts a single-byte character into a corresponding wide character.  If the character is EOF or not valid in the ini-
     tial shift state, btowc() returns WEOF.

     The wctob() function converts a wide character into a corresponding single-byte character.  If the wide character is WEOF or not able to be
     represented as a single byte in the initial shift state, wctob() returns WEOF.

     While the btowc() and wctob() functions use the current locale, the btowc_l() and wctob_l() functions may be passed locales directly. See
     xlocale(3) for more information.

LEGACY SYNOPSIS
     The include file <stdio.h> is not necessary for these functions.

STANDARDS
     The btowc() and wctob() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY
     The btowc() and wctob() functions first appeared in FreeBSD 5.0.
