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 endof-file
     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 subse-quent subsequent
     quent attempts to read will return WEOF until the condition is cleared with clearerr(3).

SEE ALSO
     ferror(3), fopen(3), fread(3), getc(3), getwc_l, putwc(3), stdio(3), ungetwc(3)

STANDARDS
     The fgetwc(), getwc(), and getwchar() functions conform to ISO/IEC 9899:1999 (``ISO C99'').
