I'm trying to make a multithreaded initialization routine that is going to divvy up the task based on the number of concurentThreadsSupported. It's a constructor calling another member function, but no matter how I seem to format it, I can't seem to call the other member function as a thread function. So how would I go about properly threading a member function, with arguments, from inside a class?
And before it's asked, I'm not using "using namespace std;", instead, I'm using "using std::vector;" and others as required.
Universe::Universe(const unsigned __int16 & NumberOfStars, const UniverseType & Type, const UniverseAge & Age) { thread *t = new thread[concurentThreadsSupported-1]; for (unsigned __int32 i = concurentThreadsSupported - 1; i > 0; i--) { //problem line t[i] = thread(&Universe::System_Spawner, i, NumberOfStars / concurentThreadsSupported, Type, Age); } for (int i = concurentThreadsSupported - 1; i > 0; i--) { t[i].join(); cout << "Thread joined" << endl; } delete[] t; } void Universe::System_Spawner(const unsigned __int16 threadNumber, const unsigned __int16 NumberOfStars, const UniverseType & Type, const UniverseAge & Age) { cout << "Inside Thread" << endl; } The error that I get is
