Sample text

If you don’t decide before the std::thread object is destroyed, then your program is terminated (the std::thread destructor calls std::terminate()). It’s therefore imperative that you ensure that the thread is correctly joined or detached, even in the presence of exceptions. 3 for a technique to handle this scenario. Note that you only have to make this decision before the std::thread object is destroyed—the thread itself may well have finished long before you join with it or detach it, and if you detach it, then the thread may continue running long after the std::thread object is destroyed.

How do you launch these threads, how do you check that they’ve finished, and how do you keep tabs on them? The C++ Standard Library makes most thread-management tasks relatively easy, with just about everything managed through the std::thread object associated with a given thread, as you’ll see. For those tasks that aren’t so straightforward, the library provides the flexibility to build what you need from the basic building blocks. In this chapter, I’ll start by covering the basics: launching a thread, waiting for it to finish, or running it in the background.

One way to handle this internally is to run each document-editing window in its own thread; each thread runs the same code but with different data relating to the document being edited and the corresponding window properties. Opening a new document therefore requires starting a new thread. The thread handling the request isn’t going to care about waiting for that other thread to finish, because it’s working on an unrelated document, so this makes it a prime candidate for running a detached thread.
