how to get string from a line of strings?

Question

I have following string:

"hw_core_detectionhook::Iocard const*"

I have to get only first part, i.e all text present before space, i.e I need the "hw_core_detectionhook::Iocard" part only.

std::stringstream ss;

ss << "hw_core_detectionhook::Iocard const*";

std::string s;

ss >> s;

std::cout << s;

Output:

hw_core_detectionhook::Iocard

thanks but above expression wil provide me second part i.e const* – balaji Apr 19 '11 at 13:08
I've tried and it seems to provide the first part: http://www.ideone.com/Q84m9. If s.find_first_of would be the first argument - then it would provide " const*". – maxim1000 Apr 19 '11 at 13:19
