putwchar—write a wide character to standard output #include <wchar.h>
wint_t putwchar(wchar_t wc);
wint_t _putwchar_r(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.
