Thread launch

In the previous example, we saw that the initialization function is passed as an argument to the std::thread constructor, and the thread gets launched. This function runs on its own thread. The thread launch happens during the thread object's construction, but the initialization functions can have other alternatives as well. A function object is another possible argument in a thread class. The C++ standard library ensures that the std::thread works with any callable type.

The modern C++ standard supports threads to be initialized through:

• Function pointers (as in the previous section)
• An object that implements the call operator
• Lambdas

Any callable entity is a candidate for initializing a thread. This enables the std::thread ...
