四、线程局部存储 线程局部存储(Thread Local Storage,TLS)是每个线程独有的数据存储区域,适合存储线程特有的状态信息。静态变量可以声明为__thread(GCC)或使用C11中的_Thread_local关键字以使每个线程拥有变量的独立副本,从而实现线程安全。 线程局部存储示例: _Thread_local static int thread_local_var; void thread...
动态定义的局部变量在程序执行出其作用域时发生析构,线程local生命周期(thread storage duration)的对象在线程初始化函数返回后发生析构,或调用线程exit是析构。线程生命周期的对象全部在静态变量之前析构,静态变量按照后构造的先析构的栈式顺序释放。 此特性称为“Dynamic Initialization and Destruction with Concurrency...
Thread-Relative Static Fields Data Slots See also You can use managed thread local storage (TLS) to store data that's unique to a thread and application domain. .NET provides two ways to use managed TLS: thread-relative static fields and data slots. ...
Runtime emulating static thread local storage of portable executable software codeA Windows process loader is emulated for dynamic TLS data allocation during respective application runtime. A total required TLS data block size is initially calculated and corresponding data block duplicates are created ...

但是因为APP实际上也是DLL,这就导致连S60的主程序也不能使用可写的全局变量,这个在某些时候就成了问题,全局变量毕竟是一个重要的实现手段。对此,S60提供了线程局部存储(thread local storage)来解决问题。 TLS的关键是两个函数: void Dll::SetTls(void*)和void* Dll::Tls() ...
MATLAB dynamically loads some libs with static TLS (thread local storage, e.g. see gcc compiler flag -ftls-model). Loading too many such libs => no space left. Until now mathwork's only workaround is to load the important(!) libs first by using them early (they suggest to put "...

Storage class is a property of an object: The actual thing (value) being stored. Scope is a property of an identifier: The name used to refer to an object (or a type or a function). There are four storage durations: static, thread, automatic, and allocated. There are four kinds of ...
