std::wstring to wchar_t *

I have a std::wstring variable and I need to get a wchar_t * from that std::wstring variable. I tried using the c_str() method from std::wstring but that returns a const wchar_t * so I get the following error

Code:

---

error C2440: '=' : cannot convert from 'const wchar_t *' to 'wchar_t *'
        Conversion loses qualifiers

---

How can I fix that?

I think the only way is to use the std::wstring::copy method to copy the contents into a buffer.

Or you could just re-cast it:

C style:

wchart* wc = (wchart*)s.c_str();

or C++ style:

wchart* wc = const_cast<wchar_t*>( s.c_str() );

Be sure you understand why you are removing the const (ie. don't then attempt to modify the string contents). It is there for a reason--because the contents of the string pointer is not meant to be modified.
