NAME
     ffggeettwwcc, ggeettwwcc, ggeettwwcchhaarr - get next wide character from input stream

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS

     ##iinncclluuddee <>

     wintt
     ffggeettwwcc(FILE *stream);

     wintt
     ggeettwwcc(FILE *stream);

     wintt
     ggeettwwcchhaarr();

DESCRIPTION
     The ffggeettwwcc() 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 ggeettwwcc() function acts essentially identically to ffggeettwwcc().

     The ggeettwwcchhaarr() function is equivalent to ggeettwwcc() with the argument stdin.

     Extended locale versions of these functions are documented in getwcl(3).
     See xlocale(3) for more information.

RETURN VALUES
     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).

STANDARDS     The ffggeettwwcc(), ggeettwwcc() and ggeettwwcchhaarr() functions conform to ISO/IEC
