std::string comparison (check whether string begins with another string)

I need to check whether an std:string begins with "xyz". How do I do it without searching through the whole string or creating temporary strings with substr().


I would use compare method:

std::string s("xyzblahblah");
std::string t("xyz")

if (s.compare(0, t.length(), t) == 0)
// ok
