In a multi-threaded environment, it is common practice to use locks to control access to shared resources in order to ensure data consistency and safety, and prevent issues arising from data races and concurrent access.
Producer-consumer pattern: In this pattern, producer threads and consumer threads need to cooperate, using locks to achieve synchronization between producers and consumers.
ReadWrite Lock: In scenarios involving reading and writing, reading operations can be done concurrently, but writing operations need to be done exclusively. By using a read-write lock, read-write separation can be achieved, enhancing the system’s concurrency performance.
Waiting for notification mechanism: In certain scenarios, threads may need to wait for specific conditions to be met before continuing execution. In this case, the lock’s waiting and notification mechanism can be used to achieve thread waiting and waking up.
Limiting the number of concurrent threads: Use locks to control the number of concurrent threads, restrict the number of threads executing simultaneously, and prevent excessive consumption of system resources.
