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

NAME
       putwchar - write a wide character to standard output

SYNOPSIS
       #include <wchar.h>

       wint_t putwchar(wchar_t wc);

DESCRIPTION
       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 con-
       version error occurs, it sets errno to EILSEQ and returns WEOF.  Other-
       wise, it returns wc.

       For a nonlocking counterpart, see unlocked_stdio(3).

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

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

NOTES
       The behavior of putwchar() depends on the LC_CTYPE category of the cur-
       rent locale.

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