fputwc - write a wide character to a FILE stream
#include <wchar.h>
wint_t fputwc (wchar_t wc, FILE* stream);wint_t putwc (wchar_t wc, FILE*
stream);
The fputwc function is the wide-character equivalent
of the fputc 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 performs identically to fputwc.
The fputwc
function returns wc if no error occurred, or WEOF to indicate an error.

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