C # implement producer and consumer queues, In the development process, we often encounter a scenario where we need to obtain some data from a place, process the data, and save it in the database. Private void FetchData () {} private void SaveData () {} static void Main (string [] args) {for (int I = 0; I For example, if the preceding code example is executed sequentially, the execution will be slow becaus

Linux multithreading practice (6) Use Posix condition variables to solve producer and consumer problems In the previous article, we have already discussed how to use semaphores to solve the producer and consumer problems. Under what circumstances should we introduce conditional variables? Assume that there is a shared

Turn https://www.oschina.net/code/snippet_111708_25438This is a classic question, the essence of my solution is to abstract the problem into the producer consumer model, but it is a special producer consumer model, there are two requirements:1, buffer size is 1 (with a Boolean variable to represent it)2. The buffer is
