usinfg c++, how would you check if a cd-rw is blank...

[jaepi]

hello there, im currently doing some programming in burning an iso file using c++ and LINUX...is it possible to check if a medium(cd-rw) is empty or has a data inside...because im going to make a function that checks if a medium is blank or not, like:

if(cd-rw is empty){
   burn files
}else{
   empty cd-rw
   burn files
}

kinda like that...
thanks
peace... \m/

Check the cd-rw driver api documentation if any.
