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 VALUEThe fgetwc function returns the next wide-character from the stream, or WEOF.ERRORSApart from the usual ones, there is
