Question

I just tested something like this:

boost::thread workerThread1(boost::bind(&Class::Function, this, ...);
boost::thread workerThread2(boost::bind(&Class::Function, this, ...);

and it works fine. What i now want, is to create as many Threads as i have objects in a list. I have experimentet with boost::foreach and this works fine. But i have problems with the names of the threads.

So simplified the code looks like this:

for
{
    boost:thread name(...);
}

but of course name cant be right here in the loop because it overwrites itself and isnt accessible after the loop. How do i create the threads so that i can join them all after all have been created?

Answer 1

Can you not just create a list (or similar) of threads and then just create them and add to the list.

Something like the following (which is likely more pseudo code that anything 🙂 )

list<boost::thread*> threads;

for
{
    boost::thread* name = new boost::thread(...);
    threads.push_back(name);
}

As mentioned in another answer you can use smart pointers which would be better and you mentioned you have a defined number of threads so an array/vector would be a better choice but as I said the code above isn’t perfect anyway
