samples_available does not return the number of samples, only 1 or 0.

[cboulay]

According to the docstring, samples_available() is supposed to return the number of samples in the buffer.

liblsl/src/stream_inlet_impl.h

Lines 301 to 305 in 1eaaf08

	/**
	* Query the current size of the buffer, i.e. the number of samples that are buffered.
	* Note that this value may be inaccurate and should not be relied on for program logic.
	*/
	std::size_t samples_available() { return (std::size_t)(!data_receiver_.empty()); }

But it returns (std::size_t)(!data_receiver_.empty());, and data_receiver_.empty() returns a boolean sample_queue_.empty();

liblsl/src/data_receiver.h

Line 71 in 1eaaf08

bool empty() { return sample_queue_.empty(); }

So samples_available() will only ever return 0 or 1.
