Obtains an input event from sequencer. The event is created via snd_seq_create_event(), and its pointer is stored on ev argument.<p>
This function firstly receives the event byte-stream data from sequencer as much as possible at once. 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.<p>

If events remain on the input buffer of user-space, function returns the total byte size of events on it. If fetch_sequencer argument is non-zero, this function checks the presence of events on sequencer FIFO When events exist, they are transferred to the input buffer, and the number of received events are returned. If fetch_sequencer argument is zero and no events remain on the input buffer, function simply returns zero.<p>
