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 function. It writes the wide character wc to stdout. If ferror(std-
out) 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 non-locking counterpart, see unlocked_stdio(3).
RETURN VALUE
The putwchar function returns wc if no error occurred, or WEOF to indicate an error.
CONFORMING TO
ISO/ANSI C, UNIX98
NOTES
The behaviour 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.
