putwchar(3)             Library Functions Manual             putwchar(3)

NAME         top

       putwchar - write a wide character to standard output

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <wchar.h>

       wint_t putwchar(wchar_t wc);

DESCRIPTION         top

       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).

RETURN VALUE         top

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

HISTORY         top

       POSIX.1-2001, C99.

NOTES         top

       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.
