NAME    [Toc]    [Back]

     fgetwc, getwc, getwchar, - get next wide-character from input stream

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <stdio.h>
     #include <wchar.h>

     wint_t
     fgetwc(FILE *stream);

     wint_t
     getwc(FILE *stream);

     wint_t
     getwchar();

DESCRIPTION    [Toc]    [Back]

     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.

RETURN VALUES    [Toc]    [Back]

     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).
