I would like to find the names of disks available on a system.  Currently
I'm looking through the DevInfo list.  The disk names are there.  By looking
at dol_Type, I can determine if the entry is for a device or not.  The
problem is how to figure out if it's a disk or not.  Right now I look
for a startup message, and examine it to see if it looks like a disk
startup message.

I'm not happy with this method.  It doesn't find the ram disk, and it may
find a device which is not a disk.  Anybody have any suggestions?

Here's what I'm doing now.

    RootNode = (struct RootNode *)DOSBase->dl_Root;
    DosInfo  = (struct DosInfo *)BADDR(RootNode->rn_Info);
    Devices  = (struct DosList *)BADDR(DosInfo->di_DevInfo);
    
    for(Device = Devices;
        Device;
        Device = (struct DosList *)BADDR(Device->dol_Next))
    {
        if (Device->dol_Type == DLT_DEVICE
        &&  (Startup = (struct FileSysStartupMsg *)
                    BADDR(Device->dol_misc.dol_handler.dol_Startup))
        &&  (DosEnvec = (struct DosEnvec *)BADDR(Startup->fssm_Environ))
        &&  DosEnvec->de_Surfaces < 20
        &&  DosEnvec->de_Surfaces > 0)
            ;
        else
            ;
            
        Name =  (char *)BADDR(Device->dol_Name);
        Name++;
        printf("%08x: %d %s\n", Device, Device->dol_Type, Name);
    }
