Function pthread_detach

* @brief Marks a thread as detached, allowing its resources to be automatically released upon termination. * * The `pthread_detach` function separates the specified thread from the calling thread. Once a thread is detached, * its resources will be automatically reclaimed by the system upon the thread's termination. A detached thread cannot * be joined using `pthread_join`. * * @param[in] thr
