Defined in header <wchar.h>
wint_t fgetwc( FILE *stream );		(since C95)
wint_t getwc( FILE *stream );		(since C95)

Reads the next wide character from the given input stream. getwc() may be implemented as a macro and may evaluate stream more than once.

Parameters

stream

-

to read the wide character from

Return value

The next wide character from the stream or WEOF if an error has occurred or the end of file has been reached. If an encoding error occurred, errno is set to EILSEQ.
