fgetwc, getwc - read a wide character from a FILE stream
wint_t fgetwc(FILE *stream);
wint_t getwc(FILE *stream);
The fgetwc() function is the wide-character equivalent of the
fgetc(3) 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 functions identically to
fgetwc(). 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).
On success, fgetwc() returns the next wide-character from the stream.
Otherwise, WEOF is returned, and errno is set to indicate the

In the absence of additional information passed to the
fopen(3) call, it is reasonable to expect that fgetwc() will
actually read a multibyte sequence from the stream and then convert it to a
