Removing a Device Entry

When a device is permanently removed from the system, the information pertaining to the device must be removed from the Name Registry. When a name entry is removed from the Registry, all properties associated with that entry are automatically removed as well. Listing 10-14 illustrates removing a device entry from the Registry.

Note

In the current Mac OS, all children of a parent entry are removed when the parent is removed. Removing a parent entry, thereby creating orphan entries, may not be supported in future releases.

    OSErr err = noErr;

    RegEntryID entry;



/* from previous example */

    err = JoePro_FindEntry(name, &entry);

    if (err == noErr) {

        err = JoePro_RemEntry(&entry);

        RegistryEntryIDDispose(&entry);

    }

    return err;

}
