You can do this if you want an actual copy of the string (vital if the stringstream object is going to go out of scope at some point):

const char *p = new char[ss.str().size()+1];
strcpy(p, ss.str().c_str());

...

delete [] p;

As discussed in comments below, you should be wary of doing it like this (manual memory management is error-prone, and very non-idiomatic C++). Why do you want a raw char array?
