the Pid of the process, you can send a message to it.5. Message delivery is considered unreliable and is not guaranteed for transmission.6. One process should be able to detect failures in another process and be aware of the cause of the failure.It is important to note that the concurrency provided by COPL must be true concurrency, so objects that exist in the form of processes are truly concurrent, and interprocess messaging is a true asynchronous message, unlike many object-oriented languages

-off represents my thoughts and perceptions of love or life. Each of the words in the dialogue is carefully written, perhaps others will feel very frustrated, but I do not care, this is what I agree with. Every click will have a note, each of which is a chorus or a familiar part of Jay's song, representing my respect for the idol.No matter how I can not imagine I could actually make this game, my technology may not be so good, but at least I would like to try to make the effect I want at least t

OverviewThe so-called distributed system can be split and deployed to multiple servers on the system, usually through the network to interact.In the above concept, we can see that there are two core concepts:[1] One is the system can be split, which and our monomer application is two extreme performance[2] can be deployed on more than one serverCommonly, we often compare the concepts of distributed systems and hierarchies to clusters.Layering: This conceptCluster: Refers to the integration of

Set the storage domain of the Variable I think it is inappropriate to answer questions in this way. The following is my answer: The static type declaration has three main purposes in the C language: 1, Declare static local variables. 2, Declare static external global variab

Multithreading 001, multithreading In many cases, we expect to implement this function: start some sub-threads in the main thread, and wait until all sub-threads finish executing, the main thread continues to execute. For example, the boss assigns tasks and many workers start to work. After all workers finish their work, the boss checks the jobs. Solution Analysis:Implement through join The first method is to directly call the join method of the threa

ORACLE-018: ORACLE tip 001 string processing, oracle-018oracle 1. truncate a string Oracle uses a function substr to intercept a string. The parameter is substr (string, start position, and truncation length ), For example, if the string 123,112 needs to be removed by a comma, the truncation function is as follows: Select substr ('1970, ', 0, length ('1970,')-1) from dual; Result: 123,112 2.
