[Boost-users] Mismatch and regex newbie problem

Hello,
I'm using the boost regex library to search short expressions in large 
strings. The code below works fine but it almost does what ever i want. The 
thing i'm missing and that i'm not sure to handle are the mismatches. 
Basically when i look for a regex in a string i want to have the possibility 
to get the number of mismatches and their respective positions. I read 
through the docs and saw that the boost_check may do the work. Well the 
think is that i'm not sure how to use it with my code and since the boost 
library is quite complex it would be great if somebody could help to move 
forward.

How can i use the code below to get the mismatches and their positions with 
boost_check ???

#####Setting the regex
.....
re = "test";
boost::regex *regex = new boost::regex(re,boost::regbase::icase);
.....

#######Getting the matched
.......
std::string::const_iterator start = in.begin();
  std::string::const_iterator end = in.end();
  boost::smatch match;
  while (boost::regex_search(start,end,match,*regex,boost::match_extra))
      {
        cout << match.[0] << endl;
        start = match[0].second;
      }

#############Getting the mismatches ???
How ???

Any help would be extemely helpful !!!
