Parsing list of strings ending with double NULL [closed]

How to parse in c++ list of null-terminated Unicode strings where the list is terminated with two NULL characters?

---

There's this little example on Raymond Chen's blog (which, perhaps not surprisingly, is the first find in Google for "double null terminated string"):

This reinterpretation of a double-null-terminated string as really a list of strings with an empty string as the terminator makes writing code to walk through a double-null-terminated string quite straightforward:

> for (LPTSTR pszz = pszzStart; *pszz; pszz += lstrlen(pszz) + 1) {  ...
> do something with pszz ... }

The LPTSTR and lstrlen are wrappers which change depending on whether or not _UNICODE is set.

You simply build a list of strings and abort when one is empty:

std::vector<std::string> result;
result.push_back( std::string() );
while (std::cin) {
    char c = std::cin.get();
    if ( c == 0 ) { 
        if ( result.back().empty() ) { result.pop_back(); return; }
        else result.push_back(std::string()); }
    } else {
        result.back().push_back(c);
    }
}
