ThreadStart 和 ParameterizedThreadStart 是不是必须的?

在创建线程时:创建不带参数的线程可用ThreadStart;创建带一个object参数的线程可用ParameterizedThreadStart。但有时我们看到有些人的代码又没有用这两个。比如:Threadthread1=newThread(MyThread);thread1.Start();Threadthread2...

throw 和 throws 的区别?

1、throw作用在方法内,表示抛出具体异常,由方法体内的语句处理;一定抛出了异常;2、throws作用在方法的声明上,表示抛出异常,由调用者来进行异常处理;可能出现异常,不一定会发生异常;...

PHP安装threads多线程扩展

php5.3或以上,且为线程安全版本。apache和php使用的编译器必须一致,通过phpinfo()查看ThreadSafety为enabled则为线程安全版,通过phpinfo()查看Compiler项可以知道使用的编译器一、下载pthreads扩展下载地址:http://windows.php.net/downl...

SuspendThread

SuspendThread是挂起指定的线程,不同于Sleep只能挂起其所在的线程并在时间间隔超过后自动回复,而SuspendThread挂起的线程则需要使用ResumeThread回复。SuspendThread函数原型如下:SuspendThread函数原型如下:DWORDWINAPISuspendThread(HA...

ResumeThread

ResumeThread可以恢复被SuspendThread挂起的线程的执行。ResumeThread函数原型:DWORDWINAPIResumeThread(HANDLEhThread);如果函数成功,返回值是线程的上一个挂起计数。如果函数失败,返回值为(dword)-1。要获取扩展错误信息,请调用GetLastEr...

线程锁、threading.local(flask源码中用的到)、线程池、生产者消费者模型

一、线程锁  线程安全,多线程操作时,内部会让所有线程排队处理。如:list/dict/Queue  线程不安全+人(锁)=>排队处理1、RLock/Lock:一次放一个  a、创建10个线程,在列表中追加自己,如下代码:importthreadingv=[]deffunc(arg):v.append(arg)p...
