getwc(3)                 BSD Library Functions Manual                 getwc(3)


NAME

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


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

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

     wint_t
     fgetwc(FILE *stream);

     wint_t
     getwc(FILE *stream);

     wint_t
     getwchar(void);


DESCRIPTION

     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.

     Extended locale versions of these functions are documented in getwc_l(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 fgetwc(), getwc(), and getwchar() functions conform to ISO/IEC
     9899:1999 (``ISO C99'').
