PUTWCHAR(3)               Linux Programmer's Manual              PUTWCHAR(3)

NAME         top

       putwchar - write a wide character to standard output

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.

CONFORMING TO         top

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