pthread semaphore example

"Semaphores are used in multi-threaded multitasking, where one thread completes an action by telling another thread about the semaphore, and the other thread is doing some action (where everyone is blocking when they are semtake). The mutex is used

"The semaphore is synchronized with multi-threaded multitasking, and one thread completes an action by telling the other thread that the other thread is going to do some action (where everyone is blocking when they are semtake)." The mutex is used

Semaphore (Semaphore): sometimes referred to as a semaphore, is a facility used in a multithreaded environment and can be used to ensure that two or more critical sections of code are not called concurrently. The thread must acquire a semaphore

In gemfield's article "from pthread to qthread", we learned about the basic usage of threads, but most of the content was said to be discussed in this article, that is, thread synchronization. Gemfield has a metaphor in "from process to thread", so
