This queue enqueues raw, unparsed MIDI packets, and outputs complete MIDI messages to a write queue.
Use this queue if the MIDI API you're interfacing with gives you raw MIDI bytes that must be parsed.

Called to create a new raw input write queue. The write_queue
argument is the queue to write parsed messages to. The optional max_packets
argument specifies the number of packets that can be enqueued in the internal queue. The optional max_packet_data
argument specifies the total number of MIDI bytes that can be put in the internal queue, AND the maximum size for an event that can be written to the write queue.

Override this method to specify what happens when there isn't enough room in the ringbuffer to contain a parsed event. The default method outputs an error message.

Override this method to specify what happens when a parsed event can't be written to the write queue because the event's size exceeds the total possible space in the write queue. The default method outputs an error message.

Enqueues a data packet in the write queue of size
bytes contained in buffer
that will be sent the absolute time specified by time
. This method should not block unless 1.) this write queue represents the actual outbound MIDI connection, 2.) the MIDI event is being sent now, meaning that time
is less than or equal to now, and 3.) the method is not being called in the process thread. The method should return OK
if the event was enqueued, BUFFER_FULL
if the write queue isn't able to accept the event right now, BUFFER_TOO_SMALL
if this write queue will never be able to accept the event because the event is too large, EVENT_EARLY
if this queue cannot schedule events ahead of time, and EN_ERROR
if an error occurs that cannot be specified by another return code.
Implements Jack::JackMidiWriteQueue.

size_t JackMidiRawInputWriteQueue::GetAvailableSpace | ( | ) |
Returns the maximum size event that can be enqueued right now.

jack_nframes_t JackMidiRawInputWriteQueue::Process | ( | jack_nframes_t | boundary_frame = 0 | ) |
The Process()
method should be called each time the EnqueueEvent()
method returns OK
. The Process()
method will return the next frame at which an event should be sent. The return value from Process()
depends upon the result of writing bytes to the write queue:
-If the return value is '0', then all complete events have been sent successfully to the write queue. Don't call Process()
again until another event has been enqueued.
-If the return value is a non-zero value, then it specifies the frame that a pending event is scheduled to sent at. If the frame is in the future, then Process()
should be called again at that time; otherwise, Process()
should be called as soon as the write queue will accept events again.
