FGETWC (3)
read a wide character from a FILE stream
SYNOPSIS
#include <stdio.h>
#include <wchar.h>
wint_t fgetwc (FILE* stream );
wint_t getwc (FILE* stream );
DESCRIPTION
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 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.
RETURN VALUE
The fgetwc function returns the next wide-character from the stream, or
WEOF.
ERRORS
Apart from the usual ones, there is
EILSEQ
The data obtained from the input stream does not
form a valid character.

SEE ALSO
NOTES
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.
