For a simple program, you can use the Multiprocessing module instead of the Threading module, a small number of changes can be. However, the multiprocessing module also addresses the biggest challenge for the collaboration process to encounter : passing data between processes. To summarize, there is a Gil lock in Python, which leads to the inability and normal use of threads, but for IO-intensive jobs, because all plug-

Console.WriteLine (Dosome (ref shit));//returns 4 console.readkey (); } public static int dosome (ref int shit) { shit++; return shit; } }All of this is the difference between the value-based and by-reference delivery of value types in C #. By the way, in C #, passing by reference is divided into ref and out, and these two keywords are used to denote passing by reference, that is, the timing of the initialization of an a

place according to the JMP_BUF parameter and then to the next statement of the setjmp execution, Note that when setjmp first runs, the return value is 0. Now let's take a look at the following examples to understand the setjmp and longjmp operating mechanisms: #include Run Result:It can be judged that the longjmp call does jump to the setjmp after the execution of the statement, because our program is written in the dead loop, so will continue to die cycle. Now, let's see why we can't use set

storage engine such as InnoDB prompts for a circular dependency and returns an error immediately. Otherwise the deadlock will cause the query to be very slow. Some other bad practice is to wait for the timeout and then give up. The current InnoDB handles deadlocks by rolling back transactions that hold the least exclusive row-level locks. (Reference metric for almost the simplest rollback) The behavior of the lock is in the order that the storage engine determines. As a result, some storage en
