How to determine if a CD is in a CD-ROM

Question

I was wondering if there is a Windows API that can tell me if there is an empty CD inside the CD-ROM / DVD-Rom.

I already looked at GetVolumeInformation (), but this only returns information about the real CD-ROM, and not about the media that is inside it if it has a CD or not.

All I'm trying to do is see if there is a disk on disk or not, and return a boolean value.

Thanks for any help
