Looking for C code reading /dev/dsp value

[Rein Couperus <rein@couperus.com>]

Hello all,

I want to measure the average amplitude value of an audio noise spectrum put 
into the sound card of a laptop (I need it for automatic noise bridge project 
to be built into tlf) . Could someone point me to some SIMPLE C-code which 
does nothing but read one actual value from /dev/dsp? Is there a register or 
memory location I could read? I am no hardware expert, and I don't have time 
to become one :)
