示例1: locker

partition_id childID, int32* childChangeCounter, off_t newOffset,

int32 descendantCount)
{
#if 0
KDiskDeviceManager *manager = KDiskDeviceManager::Default();
// get the partition
KPartition *partition = manager->WriteLockPartition(partitionID);
if (!partition)
return B_ENTRY_NOT_FOUND;
PartitionRegistrar registrar1(partition, true);
