Pointers are not used for strings in d. string is an alias for 
immutable(char)[]. So, you can do:
```d
     import std.exception : assumeUnique; // makes char[] immutable

     string str = (new char[15]).assumeUnique;

     str = "hmm. my string!";
```

a slice in d (e.g. char[]) is roughly considered as a struct with 
a pointer and length. I also suspect that your question is not 
that simple, maybe you really need a string pointer, and I 
couldn't understand what you are actually asking. I am sorry if 
those are not what you were looking for the answers to.

Here is how you GC allocate a pointer to a string.
```d
string* strptr = new string[1].ptr;
// Since slices are reference types just use this instead:
string[] strptr = new string[1];
```
Maybe you need a pointer to the first char of a string then:
```d
string str; // allocated somehow

immutable(char)* chr = str.ptr;
```
