fgetwc, getwc - read a wide character from a FILE stream


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

   wint_t fgetwc(FILE *stream);
   wint_t getwc(FILE *stream);


   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).


   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.


   Apart from the usual ones, there is

   EILSEQ The data obtained from the input stream does not  form  a  valid

   The behavior of fgetwc()  depends  on  the  LC_CTYPE  category  of  the
   current 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.
