NAME

6       putwchar - write a wide character to standard output
7

LIBRARY

9       Standard C library (libc, -lc)
10

SYNOPSIS

12       #include <wchar.h>
13
14       wint_t putwchar(wchar_t wc);
15

DESCRIPTION

17       The  putwchar()  function  is  the  wide-character  equivalent  of  the
18       putchar(3) function.  It writes the wide character wc  to  stdout.   If
19       ferror(stdout) becomes true, it returns WEOF.  If a wide character con‐
20       version error occurs, it sets errno to EILSEQ and returns WEOF.  Other‐
21       wise, it returns wc.
22
23       For a nonlocking counterpart, see unlocked_stdio(3).
24

RETURN VALUE

26       The putwchar() function returns wc if no error occurred, or WEOF to in‐
27       dicate an error.

NOTES

46       The behavior of putwchar() depends on the LC_CTYPE category of the cur‐
47       rent locale.
48
49       It is reasonable to expect that  putwchar()  will  actually  write  the
50       multibyte sequence corresponding to the wide character wc.
