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
