How to allocate memory for a double pointer

dreamuser · #1 03-Jul-2008, 12:18

I have the following:

BoundedQueue<Item> * * Body;

How do I allocate memory for Body?

Body = new BoundedQueue<Item>* does not work

It would help if you provide both the error received & what is the purpose of Body. Are you simply wanting an array of pointers, a two-dimensional array, or what? Likewise, what compiler are you using?

The following compiles as expected with GCC 3.3.5:

CPP / C++ / C Code:

template <class T> class foo { };

class bar { };

int 
main() {
    foo<bar> **pp = new foo<bar>*;
    
    return 0;
}

...which simply allocates space for a pointer dynamically.
