NAME

       getwc - get a wide character from a stream

SYNOPSIS

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

       wint_t getwc(FILE *stream);

DESCRIPTION

       The  getwc() function shall be equivalent to fgetwc(), except that if it is implemented as
       a macro it may evaluate stream more  than  once,  so  the  argument  should  never  be  an
       expression with side effects.

RETURN VALUE

       Refer to fgetwc() .

ERRORS

       Refer to fgetwc() .

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       Since  it  may  be implemented as a macro, getwc() may treat incorrectly a stream argument
       with side effects. In particular, getwc(*f++)  does  not  necessarily  work  as  expected.
       Therefore, use of this function is not recommended; fgetwc() should be used instead.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
