PUTWCHAR(3) Linux Programmer's Manual PUTWCHAR(3)NAMEputwchar - 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.
ATTRIBUTES
For an explanation of the terms used in this section, see
attributes(7).

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.
