编辑“︁C 语言线程终止”︁（章节）

=== 使用 pthread_cleanup_push() 和 pthread_cleanup_pop() ===  
这两个函数注册清理函数，在线程终止时自动调用。  

<syntaxhighlight lang="c">  
void cleanup_handler(void* arg) {  
    printf("Cleaning up: %s\n", (char*)arg);  
}  

void* thread_function(void* arg) {  
    pthread_cleanup_push(cleanup_handler, "Resource A");  
    pthread_cleanup_push(cleanup_handler, "Resource B");  
    printf("Thread is working\n");  
    pthread_exit(NULL);  // 触发清理函数  
    pthread_cleanup_pop(0);  
    pthread_cleanup_pop(0);  
    return NULL;  
}  
</syntaxhighlight>  

'''输出'''：  
<pre>  
Thread is working  
Cleaning up: Resource B  
Cleaning up: Resource A  
</pre>
