NAME

       putwc - put a wide character on a stream

SYNOPSIS

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

       wint_t putwc(wchar_t wc, FILE *stream);

DESCRIPTION

       The  putwc() function shall be equivalent to fputwc(), 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 fputwc() .

ERRORS

       Refer to fputwc() .

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       Since  it  may  be  implemented  as a macro, putwc() may treat a stream argument with side
       effects incorrectly. In particular, putwc(wc,*f++) need not  work  correctly.   Therefore,
       use of this function is not recommended; fputwc() should be used instead.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
