Using a *const char ** is prone to Undefined Behaviors. If there's a way to
use *std::string *instead, then try to do that.

But - if you *must *use a *const char ** [say for a 3rd party interface
that requires it] then that's as good as any method.

Be aware of the potential for an exception, and be ready to deal with it.
