fgetwc - read a wide character from a FILE stream
#include <wchar.h>
wint_t fgetwc (FILE* stream);wint_t getwc (FILE* stream);
The
fgetwc function is the wide-character equivalent of the fgetc function. It
reads a wide character from stream and returns it. If the end of stream
is reached, or if ferror(stream) becomes true, it returns WEOF. If a wide
character conversion error occurs, it sets errno to EILSEQ and returns
WEOF.
The getwc function or macro performs identically to fgetwc.
The fgetwc function returns the next wide-character from the stream,
or WEOF.

The behaviour of fgetwc 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 fgetwc will actually read a multibyte sequence
from the stream and then convert it to a wide character.
