PUTWC

Updated: 2003
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.
