请问怎么退出uloop_run的循环

1、代码情况:主线程使用pthread_create创建一个子线程后,主线程调用uloop_run进入uloop循环
2、目标:想在子线程里面调用一个函数令主线程退出uloop循环,如果没有这样的函数,子线程该如何处理能够令主线程退出uloop循环

kthread_run() 函数第二个参数(变值、限制大小2048b)的问题

for (i = 0; i < 10; i ++) { kthread_run(thread_fun, &i, "fun"); } 传入的i在线程函数中*(int *) 有时第一个传入的i(0)会变成-1、 1或别的数值 int kth_sn[2048] = 0; for (i = 0; i < 2048; i ++) { kth_sn[i] = i; kthread_run(thread_fun, &kth_sn[i], "fun"); } 当sizeof(kth_sn)大于2048的时候,编译时会报 第二个参数最大为2048字节 的错

Shared Preferences KEY_FIRST_RUN 不能在 android 1.6上运行

我使用下面的代码来检查应用程序是否是第一次运行: SharedPreferences pref = getPreferences(MODE_PRIVATE); if (!pref.contains(KEY_FIRST_RUN)) { Some operation } pref.edit().putBoolean(KEY_FIRST_RUN, false).commit(); 除了 android 1.6, 可以在别的任何版本上运行。 请问这是什么原因啊?

php threads扩展 run()方法 以及 run方法调用的方法 使用全局变量

菜鸟一枚,才接触 threads扩展 Thread 实例的 run 方法 可以同时多个一起运行。 代码如下,run去执行某些事情,肯定会用到数据库操作等等,$dbcon 是一个数据库操作对象。但是 在run中是null 如此以来,多线程要做的事情几乎就没办法做下去了.... 求大神帮帮忙。有没有其他的写法,(我试了下&$dbcon也不行,就算对象还在,但是连接已经丢失 )可以让run 使用全局变量。 class pttest extends Thread { public $url; public function __construct($url,$id) { $this->url = $url; $this->id= $id; } public function run() { global $dbcon; //var_dump($dbcon); getContentByCurl($this->url,$this->id, 'thread'); } }
