ROOT::TSpinMutex Class Reference

A spin mutex class which respects the STL interface for mutexes.

This class allows to acquire spin locks also in combination with templates in the STL such as std::unique_lock or std::condition_variable_any. For example:

ROOT::TSpinMutex m;
std::condition_variable cv;
bool ready = false;
 
void worker_thread()
{
   // Wait until main() sends data
   std::unique_lock<ROOT::TSpinMutex> lk(m);
   cv.wait(lk, []{return ready;});
   [...]
}
