4.50 putwchar—write a wide character to standard output

Synopsis

#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.
