btowc(3)                Library Functions Manual                btowc(3)

ИМЯ

       btowc - convert single byte to wide character

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <wchar.h>

       wint_t btowc(int c);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ ВОЗВРАТА

       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.

ПРИМЕЧАНИЯ

       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.
