Description:
The getwchar() function reads the next wide character from stdin.
Returns:
The next character from stdin, cast as (wint_t)(wchar_t), or WEOF if the end-of-file has been reached or if an error occurs ( errno is set).
Errors:
- EAGAIN
- The O_NONBLOCK flag is set for stdin and would have been blocked by this operation.
- EINTR
- A signal terminated the read operation; no data was transferred.
- EIO
- Either a physical I/O error has occurred, or the process is in the background and is being ignored or blocked.
- EOVERFLOW
- Cannot read at or beyond the offset maximum for this stream.
