/dev/dsp file

Hello Friends,

Normally when we read a /dev/dsp file it will be started to record and while writing data into that file it will be play back the sound.

Is it possible to monitor the device which is already opened?
It means some process is opening /dev/dsp file at the same time I have to read the data from the file.Is it possible?

How can I access busy device file?
