A thread that is to be cancelled is often referred to as the target thread.cancellation of target may occur in what scenarios?

A target thread may be canceled in scenariOS such as when it has completed its task or operation, when it has reached a predetermined cancellation point, or when it is explicitly requested to terminate by another thread, usually through a signaling mechanism. Additionally, cancellation can occur if the thread is blocked in a waiting state, depending on the cancellation strategy being used (e.g., asynchronous or deferred cancellation). Proper handling of resources and state management is crucial during this process to avoid resource leaks or inconsistent states.
