-/* USAGE: changer_find(user_data, init_fxn, slot_fxn, searchlabel)
- *
- * Searches the changer. If searchlabel is not NULL, and the changer has
- * barcode support, then changer_find will load that tape
- * first. Otherwise, changer_find will search through the tape drive
- * one by one until user_slot() returns nonzero.
- *
- * Parameters: user_data: A pointer which is not interpreted by
- * changer_find, but passed back to the
- * callback functions user_data and user_slot.
- * You can use this structure instead of
- * globals.
- * user_init: This function is called right away. Its
- * arguments are:
- * user_data: (as above)
- * rc: The results of the changer -info
- * command.
- * nslots: The number of slots in the changer.
- * backwards: Whether this changer can go
- * backwards or not. Some changers
- * can only search in one direction,
- * and then the operator must reload
- * the tapes.
- * searchable: Whether this changer has a
- * barcode reader or similar device.
- * user_slot: This function is called for every slot.
- * Searching stops when it returns
- * nonzero. Arguments are:
- * user_data: (as above)
- * rc: The results of the changer -slot
- * command.
- * slotstr: The slot which was loaded
- * device: The tape device to use to read this slot.
