Deep Analysis of mutex, semaphore, and spinlock

Mutex is a key. When a person takes the key, they can enter a room. When they come out, the key is handed over to the first in the queue. Generally, this method is used to serialize the access to the critical section code to ensure that the Code is

Thread synchronization (the role and difference between mutex and semaphore)

"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

Mutex and semaphore

Mutex)   Mutex represents a mutex data structure and is also used as a binary signal lamp. A mutex is basically a multi-task sensitive binary signal. It can be used for synchronizing multiple tasks. It is often used to protect critical code
