NAME

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

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.

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 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.
