Question

I have an application that has an array of pointers to MyObject objects:

MyObject **arr;
arr= new MyObject*[10];

The application has two threads, these threads will create and delete new MyObject() to array arr. Therefore arr[n] will be changed all the time, however the MyObject‘s themselves do not change.

Should I just declare:

volatile MyObject **arr;

Or should I go with:

MyObject ** volatile arr;

Thanks in advance

Answer 1

I think you need MyObject * volatile * arr;.

Please note though that volatile is not an atomic variable or a valid method of synchronization.
