Member Function Documentation

◆ open()

virtual int MidiDriver_Emulated::open ( )

inlinevirtual

Open the midi driver.

Returns: 0 if successful, otherwise an error code.

Implements MidiDriver.

Reimplemented in Scumm::IMuseDriver_MacM68k, and Scumm::IMuseDriver_PCSpk.

◆ isOpen()

bool MidiDriver_Emulated::isOpen ( ) const

inlinevirtual

Check whether the midi driver has already been opened.

Implements MidiDriver.

◆ getBaseTempo()

virtual uint32 MidiDriver_Emulated::getBaseTempo ( )

inlinevirtual

The time in microseconds between invocations of the timer callback.

Implements MidiDriver.

◆ readBuffer()

virtual int MidiDriver_Emulated::readBuffer	(	int16 *	buffer,
		const int	numSamples
	)

inlinevirtual

Fill the given buffer with up to numSamples samples.

Data must be in native endianness, 16 bits per sample, signed. For stereo stream, the buffer will be filled with interleaved left and right channel samples, starting with the left sample. Furthermore, the samples in the left and right are summed up. So if you request 4 samples from a stereo stream, you will get a total of two left channel and two right channel samples.

Returns: The actual number of samples read, or -1 if a critical error occurred.

Note: You must check whether the returned value is less than what you requested. This indicates that the stream is fully used up.

Implements Audio::AudioStream.

◆ endOfData()

virtual bool MidiDriver_Emulated::endOfData ( ) const

inlinevirtual

Check whether end of data has been reached.

If this returns true, it indicates that at this time there is no data available in the stream. However, there might be more data in the future.

This is used by e.g. a rate converter to decide whether to keep on converting data or to stop.

Implements Audio::AudioStream.
