If you need to create a thread with member function you can do the following:

class Something
{
   public: 
     void func_to_be_thread();
     void func_to_be_thread_advanced(const char* arg1);

     std::thread init_func();
     std::thread init_func_with_param(const char *arg1);
}

std::thread Something::init_func()
{
  return std::thread(&Something::func_to_be_thread, this);
}

Also you can do it with lambda and parameters:

std::thread init_func_with_param(const char *arg1)
{
  return std::thread([=] { func_to_be_thread_advanced(arg1); });
}

which C++ version are you using ? you can use std::thread only starting C++11 .. if you need more help with the syntax, you can check std::thread calling method of class Start thread with member function
