cond

A conditional variable is a method for synchronizing between threads, which is used to automatically block a thread until it receives a cond signal or other special case, and the condition variable must be used in conjunction with the mutex when

Thread synchronization-condition variables (cond)producer and consumer issuesBefore introducing conditional variables, let's look at producer and consumer issues: producers are constantly producing products, and consumers are constantly consuming

I. Problem solving and scope of applicationis primarily used to wait for a condition that may require another thread to satisfy this condition. The biggest difference between this and our usual pthread_mutex_lock is that the latter is generally

Today, we are far away from the slave table.-- Zhuge Liang's departure form LISP is a well-known language with a full name of list processor, the "Table processing language". It was designed by John McCarthy in 1958. Many languages, such as algo,

This article mainly introduces how to use the Queue module and Condition object to synchronize threads in Python. It is an example of how to operate with the thread programming in the threading module. For more information, see The Queue module

In Python, the Queue and Condition are used for thread synchronization. The Queue module maintains thread synchronization.Using the first-in-first-out feature of the Queue object, the data of each producer is stored in the Queue at a time, and each
