fgetwc, getwc, getwchar -- get next wide-character from input stream
Standard C Library (libc, -lc)
The fgetwc() function obtains the next input wide-character (if present)
from the stream pointed at by stream, or the next character pushed back
on the stream via ungetwc(3).
The getwc() function acts essentially identically to fgetwc().
The getwchar() function is equivalent to getwc() with the argument stdin.
If successful, these routines return the next wide-character from the
stream. If the stream is at end-of-file or a read error occurs, the routines
return WEOF. The routines feof(3) and ferror(3) must be used to
distinguish between end-of-file and error. If an error occurs, the
global variable errno is set to indicate the error. The end-of-file condition
is remembered, even on a terminal, and all subsequent attempts to
read will return WEOF until the condition is cleared with clearerr(3).

The fgetwc(), getwc() and getwchar() functions conform to ISO/IEC
9899:1999 (``ISO C99'').
