There is a method for strings called c_str(). It returns, as you might guess, a C string version of the string.

As for wstrings, I don't know anything about them (I don't do much C++ programming), but I did find some documentation. I found this page very helpful:
basic_string<charT, traits, Alloc>

Basically, string and wstring are both typedefs for a special version of basic_string. As a result, I imagine that wstring also has a c_str() method, but it probably returns a wchar_t *, not a char *. You can probably find a way to use this, however.
