NAME
putwchar - write a wide character to standard output
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wchar.h>wint_t putwchar(wchar_t \nwc\n);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 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
The putwchar() function returns wc if no error occurred, or WEOF to indicate an error.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

STANDARDS
C11, POSIX.1-2008.
HISTORY
POSIX.1-2001, C99.
NOTES
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.
