FUNCTION
<<putwchar>>---write a wide character to standard output

INDEX
	putwchar
INDEX
	_putwchar_r

ANSI_SYNOPSIS
	#include <wchar.h>
	wint_t putwchar(wchar_t <[wc]>);

	wint_t _putwchar_r(struct _reent *<[reent]>, wchar_t <[wc]>);

TRAD_SYNOPSIS
	#include <wchar.h>
	wint_t putwchar(<[wc]>)
	wchar_t <[wc]>;

	wint_t _putwchar_r(<[reent]>, <[wc]>)
	struct _reent *<[reent]>;
	wchar_t <[wc]>;

DESCRIPTION
The <<putwchar>> function or macro is the wide-character equivalent of
the <<putchar>> function. It writes the wide character wc to stdout.

The alternate function <<_putwchar_r>> is a reentrant version.  The
extra argument <[reent]> is a pointer to a reentrancy structure.

RETURNS
If successful, <<putwchar>> returns its argument <[wc]>.  If an error
intervenes, the result is <<EOF>>.  You can use `<<ferror(stdin)>>' to
query for errors.

PORTABILITY
C99
