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 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).

CONFORMING TO

POSIX.1-2001, POSIX.1-2008, 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.
