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(), but is a
macro that expands in-line.
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 rou-
tines 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 con-
dition 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'') and IEEE Std 1003.1-2001 (``POSIX.1'').
