putwchar - write a wide character to standard output

  #include <wchar.h>

  wint_t putwchar(wchar_t wc);

The putwchar*() function is the wide-character equivalent of the *putchar*(3) function. It writes the wide character wc to stdout. If ferror(stdout) becomes true, it returns *WEOF. If a wide character conversion error occurs, it sets errno to EILSEQ and returns WEOF. Otherwise, it returns wc.

For a nonlocking counterpart, see *unlocked_stdio*(3).

The putwchar*() function returns wc if no error occurred, or *WEOF to indicate an error.

For an explanation of the terms used in this section, see *attributes*(7).

POSIX.1-2001, POSIX.1-2008, C99.

The behavior of putwchar*() depends on the *LC_CTYPE category of the current locale.

It is reasonable to expect that *putwchar*() will actually write the multibyte sequence corresponding to the wide character wc.
