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.
For non-locking counterparts, see unlocked_stdio(3).
"RETURN VALUE"
The fgetwc function returns the next wide-character from the stream, or WEOF.
