Allocating a C string without heap

[Victor Porton <porton@narod.ru>]

Let we have an Ada String.

I need to pass it converted to a C string into a C library function.

Now I do it with Interfaces.C.Strings.New_String. But it is slow as it uses 
the heap and requires (not to forget incidentally!) further 
Interfaces.C.Strings.Free.

Is there a better way to do this? I mean that we would probably create a 
nul-terminated char_array (not on the heap but on the stack!) and pass the 
pointer to its first element.

This would be both safer an faster.

Can you elaborate on this?
