Sleep Disadvantage:the orderin which the blocked threads execute the critical section (CS) isleft to chance and the system. The system chooses one of the blocked threads and allows it to execute the code in the CS. Where are we going with synchronization? •There is a better way:...

Synchronization tool that does not require busy waiting Semaphore S – integer variable Two standard operations modify S: wait() and signal() Can only be accessed via two indivisible (atomic) operations wait (S) { while S <= 0 ; // no-op S--; } signal (S) { S++; } ...
82133d30 SynchronizationEvent 略去几条线程的信息。 对比KPROCESS的结构和上面Process命令得到的输出结果,可以看到,Process命令只是输出了一部分的Process的信息。如果采用!Process 0 0来获取到某特特定进程的Eprocess的地址做为Process命令的参数,就可以得到特定的Process的信息。
