You want mciSendString:

Use the "set" command:

Example:

#include <mmsystem.h>
void __fastcall TForm2::Button1Click(TObject *Sender) {
    mciSendString("set cdaudio door open", NULL, 0, NULL);
}

Interesting question, however I installed an application
by a customer recently and the setup program had an option
to eject the CD.

The Customer has 2 CD drives and the eject process ejected
the other closed CD ROM drive (heh heh) :)

Question: How to tell which drive you are in and relate it
the the drive you are ejecting...

I usually think DeviceIoControl() which uses a
CreateFile() handle, so it's easy to relate.

As to which drive, GetModuleFileName() should
contain the drive letter.
GetCommandLine() should also have the drive letter.

Here is a Delphi version using DeviceIoControl

And an old, much less complete C++
