How do I convert PWSTR to string in C++?

Question

I have the following code:

// Fetch Local App Data folder path.
PWSTR localAppData = (PWSTR) malloc(128);
SHGetKnownFolderPath(FOLDERID_LocalAppData, 0, NULL

I like Praetorina'sPraetorian's answer of just using wide string stream but if you want to convert:

char str[128];
wcstombs(str, localAppData, 128);

There is another function which goes the other way around too:

wchar_t wstr[128];
mbstowcs(wstr, "Hello World", 128);
