M_AddToSampleBuffer()

void M_AddToSampleBuffer	(	musicStream_t *	userdata,
		int	rate,
		int	samples,
		const byte *	data )

Add stereo samples with a 16 byte width to the stream buffer.

Parameters

[in]	samples	The amount of stereo samples that should be added to the stream buffer (this is usually 1/4 of the size of the data buffer, one sample should have 4 bytes, 2 for each channel)
[in]	data	The stereo sample buffer
[in,out]	userdata	The music stream
[in]	rate	The sample rate
