In order to wait for a thread, the std::thread::join( ) function has to be used. This method makes the present thread wait till the thread recognized by *this has stopped executing. For example, to block the mai
在命令窗口中执行Java编译命令时遇到“exception in thread “main” java.lang.NoClassDefFoundError”错误，通常是因为环境变量配置不正确。以下是可能的原因及解决方法：检查JAVA_HOME环境变量：确保JAVA_HOME环境变量已正确设置，并且指向你的JDK安装目录。例如，在Windows系统中，它可能设置为C:Pr...
When using thread-local variables in dynamically-loaded libraries, you need to be aware of factors that can cause a thread-local variable to not be initialized correctly: If the variable is initialized with a function call (including constructors), this function will only be called for the thre...

A joining_thread is a thread that joins at the end of its scope. Detached threads are hard to monitor. It is harder to ensure absence of errors in detached threads (and potentially detached threads). joining_thread是一种在和作用域连结的线程。分离之后的线程很难监控。很难保证分离之后(或者存在...
Because this pattern of calling Enter, accessing the protected resource, and then calling Exit is so common, the C# language offers special syntax to simplify the code. The two C# code fragments inFigure 4are identical in their function, but the second one is simpler. Using the C# lock stat...
thpool_add_work(thpool, (void*)function_p, (void*)arg_p)Will add new work to the pool. Work is simply a function. You can pass a single argument to the function if you wish. If not,NULLshould be passed. thpool_wait(thpool)Will wait for all jobs (both in queue and currently runni...
Key function nanosleep,它能提供纳秒级的延时精度,该用户空间函数对应的内核实现是sys_nanosleep,它的工作交由高精度定时器系统的hrtimer_nanosleep函数实现,最终的大部分工作则由do_nanosleep完成。hrtimer_nanosleep函数首先在堆栈中创建一个高精度定时器,设置它的到期时间,然后通过do_nanosleep完成最终的延时工作,当...
