    Command:

    fgetwc

    
    
    

    SYNOPSIS

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

    DESCRIPTION

           The  fgetwc() function is the wide-character equivalent of the fgetc(3)
           function.  It reads a wide character from stream and  returns  it.   If
           the  end  of  stream  is reached, or if ferror(stream) becomes true, it
           returns WEOF.  If a wide-character conversion  error  occurs,  it  sets
           errno to EILSEQ and returns WEOF.
    
           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.
    
           For nonlocking counterparts, see unlocked_stdio(3).
    
    
    

    RETURN VALUE

           The  fgetwc() function returns the next wide-character from the stream,
           or WEOF.  In the event of an error, errno is set to indicate the cause.
    
    
    

    ERRORS

           Apart from the usual ones, there is
    
           EILSEQ The  data  obtained  from the input stream does not form a valid
                  character.
    
    
    

    CONFORMING TO

           C99, POSIX.1-2001.
    
    
    

    NOTES

           The behavior of fgetwc() depends on the LC_CTYPE category of  the  cur-
           rent locale.
    
           In  the  absence of additional information passed to the fopen(3) call,
           it is reasonable to expect that fgetwc() will actually read a multibyte
           sequence from the stream and then convert it to a wide character.
