Hello All!  I'm having a bit of trouble using DosOpen to open my CD-ROM
drive for access (specifically to eject the disc).  Here is what I have:

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

#define INCL_DOS
#include 
#include 
#include 

VOID main(VOID)
{
    HFILE CDHandle;
    ULONG action;
    APIRET rc;
    ULONG ParmLenInOut, DataLenInOut;

    rc = DosOpen("E:",
                 &CDHandle,
                 &action,
                 0,
                 FILE_READONLY,
                 OPEN_ACTION_OPEN_IF_EXISTS,
                 OPEN_FLAGS_DASD,
                 0);

   if (rc != 0)
   {
      printf("DosOpen failed (rc = %ld)\n", rc);
      exit(EXIT_FAILURE);
   }

   rc = DosDevIOCtl(CDHandle,
                    0x80,
                    0x44,
                    NULL,
                    0,
                    &ParmLenInOut,
                    NULL,
                    0,
                    &DataLenInOut);

   if (rc != 0)
   {
        printf("DosDevIOCtl failed (rc = %ld)\n", rc);
        exit(EXIT_FAILURE);
   }

   DosClose(CDHandle);
}
