The 2011 standard adds std::move to the <utility> header. Using this template method, one can move resources between objects. This means that it can also move thread instances:

#include <thread> 
#include <string> 
#include <utility> 
 
void worker(int n, string t) { 
   // Business logic. 
} 
 
int main () { 
   std::string s = "Test"; 
   std::thread t0(worker, 1, s); 
   std::thread t1(std::move(t0)); 
   t1.join(); 
   return 0; 
} 

In this version of the code, we create a thread before moving it to another thread. Thread 0 thus ceases to exist (since it instantly finishes), and the execution of the thread function resumes in the new thread that we create.

As a result of this, we do not have to wait for the first thread to re join, but only for the second one.
