FGETWC(3)			    NEWLIB			     FGETWC(3)

NAME
       4.13 `fgetwc', `getwc'--get a wide character from a file or stream

SYNOPSIS
	    #include <stdio.h>
	    #include <wchar.h>
	    wint_t fgetwc(FILE *FP);

	    #include <stdio.h>
	    #include <wchar.h>
	    wint_t _fgetwc_r(struct _reent *PTR, FILE *FP);

	    #include <stdio.h>
	    #include <wchar.h>
	    wint_t getwc(FILE *FP);

	    #include <stdio.h>
	    #include <wchar.h>
	    wint_t _getwc_r(struct _reent *PTR, FILE *FP);

DESCRIPTION
       Use  `fgetwc'  to  get  the next wide character from the file or stream
       identified by FP.  As a side effect, `fgetwc' advances the file's  cur‐
       rent position indicator.

	  The	`getwc'	 function  or macro functions identically to `fgetwc'.
       It may be implemented as a macro, and may evaluate  its	argument  more
       than once. There is no reason ever to use it.

	  `_fgetwc_r' and `_getwc_r' are simply reentrant versions of `fgetwc'
       and `getwc' that are passed the additional reentrant structure  pointer
       argument: PTR.

RETURNS
       The  next  wide	character  cast	 to `wint_t'), unless there is no more
       data, or the host system reports a read error; in either of these situ‐
       ations, `fgetwc' and `getwc' return `WEOF'.

	  You can distinguish the two situations that cause an `EOF' result by
       using the `ferror' and `feof' functions.

PORTABILITY
       C99, POSIX.1-2001

SEE ALSO
       fgetwc is part of the library.  The full	 documentation	for  is	 main‐
       tained as a Texinfo manual.  If info and are properly installed at your
       site, the command

	      info

       will give you access to the complete manual.
