NAME

6       putwchar - write a wide character to standard output
7

SYNOPSIS

9       #include <wchar.h>
10
11       wint_t putwchar(wchar_t wc);
12

DESCRIPTION

14       The  putwchar()  function  is  the  wide-character  equivalent  of  the
15       putchar(3) function.  It writes the wide character wc  to  stdout.   If
16       ferror(stdout) becomes true, it returns WEOF.  If a wide character con‐
17       version error occurs, it sets errno to EILSEQ and returns WEOF.  Other‐
18       wise, it returns wc.
19
20       For a nonlocking counterpart, see unlocked_stdio(3).
21

RETURN VALUE

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

CONFORMING TO

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

NOTES

39       The behavior of putwchar() depends on the LC_CTYPE category of the cur‐
40       rent locale.
41
42       It is reasonable to expect that  putwchar()  will  actually  write  the
43       multibyte sequence corresponding to the wide character wc.
