The driver i am writing is purely virtual .

The role of my driver is to receive the audio data played in the application program and stream it to remote system.

Over the network?

For this purpose i need to copy the audio data from alsa buffer to my Buffer. I have no idea how this can be done. So i am looking for sample code to copy the audio data to my Buffer.

I'd bet there is no need to write any ALSA driver for this. You can either use the ALSA plugin mechanism to achive this, or even some higher level. PulseAudio for example allows seamless streaming over the network out of the box.

Why are you confident that you need to write a driver?
