Hello

I read: "The total size of a static array cannot exceed 16Mb. A
dynamic array should be used instead for such large arrays."

I want to make array which is shared but also has a large size,
e.g.

      shared WorkerClass[numberOfWorkers] myWorkerArray;

where numberOfWorkers is large.

If I try to do:

      shared WorkerClass[] myWorkerArray;
      int main()
      {
        .....
        myWorkerArray = new WorkerClass [numberOfWorkers];
      }

the compiler does not allow me to do so.

My motivation is to create a global array, which I can use in
multiple functions which are created using "spawn".

Can you please help me.

Solved! I did:

myWorkerArray = new shared WorkerClass [numberOfWorkers];

Thanks.

shared is a part of the type:

    myWorkerArray = new shared(WorkerClass)[numberOfWorkers];

Alternatively, you can initialize myWorkerArray in a 'static this' block:

class WorkerClass
{}

enum size_t numberOfWorkers = 10;

shared WorkerClass[] myWorkerArray;

static this()
{
    myWorkerArray = new shared(WorkerClass)[numberOfWorkers];
}

void main()
{}

Please also consider the D.learn newsgroup. Such threads are very helpful on that newsgroup as well. :)

Thanks a lot. Sure, I post such questions on that forum.

This should probably be "shared static this()". I'm guessing one would want this to run once before main(), not every time a thread is started.
