Herbert Bushong to Darin McBride (Orig: 07:36, Tue, Sep 03, 1996):

The topic has been covered in the past, so I'm reluctant to repost.  Since
I'm not familiar with your name, however, I will offer the solution to your
problem:

/******** Cut Here **********/

#define INCL_NOPMAPI
#define INCL_DOSDEVICES

#include 
#include 
#include 

VOID main(INT argc, PCHAR argv[])
{
    HFILE hCDHandle;
    ULONG ulAction;
    APIRET rc;
    CHAR chBuffer[4] = "CD01";

    if (argc < 2)
    {
        puts("\nSyntax: EJECT ");
        exit(EXIT_FAILURE);
    }

    rc = DosOpen(argv[1], &hCDHandle, &ulAction, 0L,
                 FILE_READONLY,
                 OPEN_ACTION_OPEN_IF_EXISTS,
                 OPEN_FLAGS_DASD | OPEN_SHARE_DENYREADWRITE,
                 0L);

    if (rc)
    {
        printf("SYS%04X: DosOpen\n", rc);
        exit(EXIT_FAILURE);
    }

    rc = DosDevIOCtl(hCDHandle, 0x0080, 0x0044,
                     &chBuffer, sizeof(chBuffer), 0L,
                     NULL, 0, NULL);

    if (rc)
    {
        printf("SYS%04X: DosDevIOCtl\n", rc);
        DosClose(hCDHandle);
        exit(EXIT_FAILURE);
    }
    DosClose(hCDHandle);
    exit(0);
}

/******** Cut here **********/

Hope this helps...
