putwchar(3) -- Linux man page

 

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(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 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.
