独占设备的分配与虚拟设备独占设备每次只能分配给一个进程使用，这种使用特性隐含着死锁的必要条件，所以在考虑独占设备的分配时，一定要结合有关防止和避免死锁的安全算法。-Exclusive distribution of equipment, exclusive equipment and virtual device can only be allocated to each use of a process, which implies the use of characteristics of the necessary conditions for deadlock, and therefore in considering the allocation of exclusive equipment, we have to combine to prevent and avoid deadlock security algorithm.
