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 in-
dicate an error.
ATTRIBUTES
For an explanation of the terms used in this section, see at-
tributes(7).

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.
