string from C function

[Andy Valencia via Digitalmars-d-learn]

I feel dumb, because this can't be as elusive as it feels.
I'm calling a C library function, and getting a char * (null 
terminated).

Now I want it to be a D string.  What's the right way to do this? 
 Performance and memory use are not important; I just want a 
simple and idiomatic way to get from point A to point B.

TIA,
Andy
