[Boost-users] Regex match problem

Hi,

I experience big troubles with regex matching. The code below should
obviously match 'abc', but does not, because it tries to match the whole
string. If r='abcdefg', then match is successfull, but if it is only 'abc'
and input is 'abcdef', the match always fails as described below.

boost::match_results<std::string::const_iterator> m;
std::string inp = "abcdefg";
boost::regex r = "abc";
if (!boost::regex_match(inp, m, r, boost::match_default))
   // always fails, don't know why

How can I successfully match 'abc' agains input 'abcdefg'?

Thank you very much in advance,
Kalin
