Detecting CD drive letters in the Win32 API...

I would like to know how I would go about detecting CD drive letters using the Win32 API. If you could, please show me an example! :)

Thanks,
Matt U.

Code:

---

#include <iostream>
using std::cout;
using std::endl;
#include <windows.h>
#include <string>
using std::string;

int main(int argc, char* argv[])
{
        const string strLookup = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        string strDrive;
        DWORD dwBits = GetLogicalDrives();
        const DWORD dwMask = 1;

        for(int i = 0;i < strLookup.length();i++){
                if(dwMask & dwBits){
                        strDrive = strLookup[i];
                        strDrive.append(":\\");
                                if(GetDriveType(strDrive.c_str()) == DRIVE_CDROM)
                                        cout << "Found CDRom " << strDrive << endl;
                }
                dwBits >>= dwMask;
        }

        return 0;
}
