GETWC(3) BSD Library Functions Manual GETWC(3)
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
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'')
and IEEE Std 1003.1-2001 (``POSIX.1'').
