No, you can use it.

Introduce a string variable which will remain instantiated throughout the
lifetime of the curl request. In your simple example, the following will
probably work:

ostringstream os ;
os << "http://curl.haxx.se" ;
string url = os.str();
curl_easy_setopt(http_handle, CURLOPT_URL, url.c_str()) ;

Um, yes... but C++ is an object-oriented language, it might be cleaner to
encapsulate both the std::string and the other curl data structures into a
C++ object. (Maybe also have a look at <http://curl.haxx.se/libcurl/cplusplus/>.)
