std::ostreambuf_iterator<CharT,Traits>::failed

bool failed() const throw();
(until C++11)
bool failed() const noexcept;
(since C++11)

Returns true if the iterator encountered the end-of-file condition, that is, if an earlier call to std::basic_streambuf::sputc (made by operator=) returned Traits::eof.

Parameters

(none).

Return value

true if this iterator has encountered the end-of-file condition on output, false otherwise.
