The exception windup process entered user code 異常終結(jié)進(jìn)程進(jìn)入用戶模式。
A process enters a process wait state when the process suspends itself , hibernates , or declares that it needs to wait for an event , resource , mutex , and so forth 當(dāng)進(jìn)程掛起自己,中斷或需要等待一個(gè)事件、資源、人工干預(yù)等時(shí),即進(jìn)入等待狀態(tài)。
A server process ' s activity was viewed as being composed of a high layer markov chain in terms of the different states the server process entered ( reflecting different requests / commands received by the server process ) , and then within each of those states , another low layer markov chain reflected the series of system calls in that particular state . in fact , this could be regarded that the dynamic activity of process depended on not only code but also current input 由于服務(wù)進(jìn)程的行為不僅于依賴進(jìn)程的代碼也依賴于當(dāng)前的輸入,所以一個(gè)服務(wù)進(jìn)程的行為可以被看成由一個(gè)高層能體現(xiàn)進(jìn)程進(jìn)入不同狀態(tài)的馬爾可夫鏈組成(對(duì)應(yīng)于服務(wù)進(jìn)程接收到的請(qǐng)求或命令) ,然后在每一個(gè)特定的狀態(tài)下是由另一個(gè)低層系統(tǒng)調(diào)用序列組成馬爾可夫鏈。
