записать широкий символ в поток FILE (write a wide character to a FILE stream)
Имя (Name)
fputwc, putwc - write a wide character to a FILE stream
Синопсис (Synopsis)
#include <stdio.h>
#include <wchar.h>
wint_t fputwc(wchar_t wc, FILE *stream);
wint_t putwc(wchar_t wc, FILE *stream);
Описание (Description)
The fputwc() function is the wide-character equivalent of the
fputc(3) function. It writes the wide character wc to stream.
If ferror(stream) becomes true, it returns WEOF. If a wide-
character conversion error occurs, it sets errno to EILSEQ and
returns WEOF. Otherwise, it returns wc.
The putwc() function or macro functions identically to fputwc().
It may be implemented as a macro, and may evaluate its argument
more than once. There is no reason ever to use it.
For nonlocking counterparts, see unlocked_stdio(3).
Возвращаемое значение (Return value)
On success, fputwc() function returns wc. Otherwise, WEOF is
returned, and errno is set to indicate the error.
Ошибки (Error)
Apart from the usual ones, there is
EILSEQ Conversion of wc to the stream's encoding fails.

Примечание (Note)
The behavior of fputwc() depends on the LC_CTYPE category of the
current locale.
In the absence of additional information passed to the fopen(3)
call, it is reasonable to expect that fputwc() will actually
write the multibyte sequence corresponding to the wide character
wc.
