Rvalue references

rvalue.cpp
// How to convert lvalue to rvalue, because the compiler treats a named rvalue reference as an lvalue
// and an unnamed rvalue reference as an rvalue
// https://docs.microsoft.com/en-us/cpp/cpp/rvalue-reference-declarator-amp-amp?view=vs-2017#additional-properties-of-rvalue-references
std::vector<std::thread> thread_list;
for (int i = 0; i < 5; i++)
{
std::thread t(thread_proc, dist(engine));
// convert to rvalue explicitly
thread_list.push_back(static_cast<std::thread&&>(t));
// or create rvalue by default - temporary object cannot be referenced elsewhere
thread_list.push_back(std::thread(thread_proc, dist(engine)));
