Get the number of events that could not be written to @a port_buffer.
This function returning a non-zero value implies @a port_buffer is full. Currently the only way this can happen is if events are lost on port mixdown.
@param port_buffer Port to receive count for. @returns Number of events that could not be written to @a port_buffer.
