Anyone know how to handle CD-ROMs under Windows?

My problem is the following>
When running a program, I want it to access a mixed-mode CD for reading files
and playing CD audio... How can I determine which of the CDs in a system with more than one CD-ROM drive is the correct one/contains the data I'm looking for... Furthermore, how do I find out, which of the drives in the system are CD-ROM drives and which have CD audio capability.
My first approach was to check out the quantity
of drives associated with the cdaudio driver
by using MCI's sysinfo command, but it doesn't work...

I've also tried about all of the functions containing system information that
I could find in the MS Win32, Mfc, Multimedia and Win95 documentations.

Does anybody know how to solve this problem? I'd appreciate any help...
