Resizing fills the circular buffer

[b.n.ryland@…]

As the following block of code demonstrates, resizing a circular buffer fills it with values and thus full() reports true when one would expect it to be false.

	boost::circular_buffer<double> cb(3);
	std::cout << cb.full() << std::endl;
	for (auto i : cb)
		std::cout << i << " ";
	std::cout << std::endl;
	cb.resize(4);
	std::cout << cb.full() << std::endl;
	for (auto i : cb)
		std::cout << i << " ";
	std::cout << std::endl;

This is an expected behaviour. What you want is set_capacity() I guess. Please read resize() and set_capacity() documentation.

Oh, right. Thanks! The documentation for this library was somewhat difficult to find from its homepage and I had not previously found set_capacity().
