Pointer

Hi,

I'm getting from a C interfaces a char**data in a System.Address. I have 
the following hypothesis:
- data is an array of n elements where n is known
- There is no memory issue (meaning data[i] with i < n is allocated)
- I do not have to free the memory (memory is managed by the C library)

How can I retrieve all my values in the C arrays using a loop to create 
some Ada String (Interfaces.C.Strings.Value)?

thanks by advance,
Sebastien
