* @brief Registers a cleanup handler to be executed when the calling thread terminates. * * The `pthread_cleanup_push` function registers a cleanup handler that is executed when the calling thread * is canceled or exits (either normally or via `pthread_exit`). The cleanup handler will be executed * in the reverse order of their registration. * * The cleanup handler can be used to release res
