C++, WCHAR[] to std::cout and comparision

I need to put WCHAR[] to std::cout ... It is a part of PWLAN_CONNECTION_NOTIFICATION_DATA passed from Native Wifi API callback.

I tried simply std::cout << var; but it prints out the numeric address of first char. the comparision (var == L"some text") doesn't work either. The debugger returns the expected value, however the comparision returns 0. How can I convert this array to a standard string(std::string)?

Thanks in advance

Solution

  • Assuming var is a wchar_t *, var == L"some text" does a pointer comparison. In order to compare the string pointed to by var, use a function such as wcscmp.
