An application can register condition(s) to be monitored by the firmware.

When a callback handler is defined, the condition(s) is(are) reported to the application asynchronously from the firmware to the handler.

The way to define a handler is as follows:

Allocate the buffer that the async event condition will be applied to.
A callback handler must be registered using the mxfAsyncEventHandlerInit() function.
The conditions to monitor must be defined using the mxfAsyncEventConditionsSet() function.

After this registration, the application can transmit data as usual and/or received asynchronous events through the callback handler.

The transmit aperiodic buffer is normally updated from the callback handler.

List of conditions

The event conditions that can be monitored are as follows:

Condition	Description
MXF_ASYNCEVENT_COND_TXAPERIODIC_BUFFER_THRESHOLD	TX Aperiodic buffer almost empty threshold reached. Add enough records to the buffer to go over the almost full threshold to clear the event.
MXF_ASYNCEVENT_COND_TX_ERROR	Transmission error detected. Only late transmit is supported, check the records time tag.
