question about exception throwing and ped_device_write.

[Sven Luther]

Hello, ...

In the process of adding amiga support to parted i came to write the
following construct :

        if (_amiga_checksum (blk) != 0) {
                switch (ped_exception_throw(PED_EXCEPTION_ERROR,
                        PED_EXCEPTION_FIX | PED_EXCEPTION_IGNORE |
                        PED_EXCEPTION_CANCEL,
                        _("%s : Bad checksum on block %d of type %s\n"),
                        __func__, block,
                        _amiga_block_id(blk->amiga_ID)))
                {
                        case PED_EXCEPTION_CANCEL :
                                return NULL;
                        case PED_EXCEPTION_FIX :
                                _amiga_calculate_checksum(AMIGA(blk));
                                ped_device_write (dev, blk, block, 1);
                        case PED_EXCEPTION_IGNORE :
                        case PED_EXCEPTION_UNHANDLED :
                        default :
                                return blk;
                }
        }

So, i check the checksum of the block, and ask if the checksum should be
fixed if it is wrong.

What am i supposed to do if the ped_device_write (dev, blk, block, 1);
fails ? In this case something is seriously wrong, and i should raise a
PED_EXCEPTION_FATAL ?
