pthread gets cancelled before releasing locks
In multithreaded programming using pthreads in C/C++, it's essential to handle thread cancellation correctly, especially when locks are involved. When a thread is canceled before releasing locks, it can lead to resource leaks and potential deadlocks. To avoid this issue, you should follow some best practices: 1. **Use Cancellation Points**: Ensure that your code has well-defined cancellation points where a thread can be safely canceled. These points are locations in your code where it's safe to terminate a thread, such as after releasing locks. 2. **Explicitly Release Locks**: Always explicitly release locks (mutexes) before a thread is canceled. You can use `pthread_mutex_unlock` to release a mutex. Failing to release a lock can lead to deadlock scenarios, where other threads may be unable to acquire the locked resource. 3. **Cancellation Cleanup Handlers**: Consider using cancellation cleanup handlers (`pthread_cleanup_push` and `pthread_cleanup_pop`) to ensure that resource
