Obtains an input event from sequencer.

Then it retrieves the first event record and store the pointer on ev. By calling this function sequentially, events are extracted from the input buffer.
<p>
If there is no input from sequencer, function falls into sleep in blocking mode until an event is received, or returns <code>-EAGAIN</code> error in non-blocking mode. Occasionally, this function may return <code>-ENOSPC</code> error. This means that the input FIFO of sequencer overran, and some events are lost. Once this error is returned, the input FIFO is cleared automatically.
<p>
Function returns the byte size of remaining events on the input buffer if an event is successfully received. Application can determine from the returned value whether to call input once more or not. </td>
